A force is mass times acceleration. Acceleration is the derivative of velocity which can also help calculate displacement.
2. The SI unit for force is the newton. The sub-unit is kg times mass over seconds squared. 
3.  At bottom of post.
4. Inertia means that an object will stay at rest or moving in a straight line unless acted upon by an outside force. Mass is a measure of inertia because inertian results in more mass.
5. Issac Newton was an English mathematician, astronomer, and physicist who lived lived from 1643 to 1727. 
6.  First law: | In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.[2][3] Second law: | In an inertial reference frame, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma.  Third law: | When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. 
7. Equilibrium is a condition in which all influences acting cancel each other, so that a static or balanced situation results. 
8) (1.6 / 2.2) = A , A = .727 m / s^2
9) (13.5 / 6.5) = M, M = 2.077 kg
10) Newton's third law states that every action has an equal and opposite reaction.
11) Mass is dependent on density and volume of an object, while weight is a measure of the effect of gravity on mass.
12) The normal force is the resistance of an object (the support of an item) when it is lying on another object. It is the perpendicular force in reference to gravity.
13) The normal force is the force that is pushing two objects together. The greater the two objects are pushed against each other, the more difficult it is to move the objects along one another. Friction is the resistance of the lateral movement of two objects against each other.
14) Static friction is the friction between two objects not relative to one another, while kinetic friction is the friction between two objects relative to one another. Static friction is what keeps an object at rest, while kinetic friction is what slows down an object in motion. The coefficients for both relate the normal force to the frictional force.

(2) The SI unit for force is Neutons, the smaller unit is gm/s^2 

(3) The attached force diagrams show varying levels of forces acting upon an object. When the forces in opposite directions cancel out, it has a net force of zero, and when the forces in opposite directions are not equivalent, there is a nonzero net force. 

(4) Inertia = mass * distance^2. Inertia uses an objects mass to determine how it will move. It assumes that an object will continue its current behavior unless another force acts upon it.

(5) Isaac Newton lived from 1643-1727 and lived in the UK. He discovered the effects of gravity.

(6) Newton's first law says that an object stays at rest if its at rest, or stays in motion when it it moving unless another force acts upon it.

Newton's second law says that all the forces put together are equal to mass times acceleration.

Newton's third law states that every action has an equal and opposite reaction.

(7) Equilibrium occurs when the sum of all the forces is equal to zero.

(8) 1.6 N = 2.2 kg * acceleration
Acceleration = .727 m/s^2

(9) 13.5 N = mass * 6.5m/s^2
13.5kgm/s^2 = mass * 6.5m/s^2
Mass = 2.077 kg

(10) Forces always act in pairs because of Newton's Third Law which states that there are always "action-reaction force pairs." This is because the force is exerted on two different objects and based on prospective the force occurs on two different objects. 

(11) Mass is measuring in Kilograms and always remains the same. It is closely related to inertia, and can not be measured directly. Weight can change based on where you are in the universe. Weight is also measure in Newtons.

(12) This is the support force exerted on an object in contact with another stable object. If a book is laying on an object the vertical force is the normal force acting on the book. However it is affected by the angle of the object. 

(13) It is proportional to normal force because friction is based on the amount of contact the object has with the stationary object it lays on. Also the friction always tries to oppose the force you apply on an object. Therefore as you try and slide the object it will face a friction force proportional to the normal force.

(14) Static friction forces from the sliding of two forces allows for some motion to occur. Therefore this involves a kinetic coefficient. Also there is stationary friction which can be calculated by the static coefficient and is the frictional force directly related to normal force. Hence, both coefficient are necessary to calculate overall friction. 

Equations: 
Force of static friction =  (coefficient of static friction) * (Normal force)
Force of kinetic friction = (coefficient of kinetic friction) * (Normal force)

Force is mass times acceleration. Force can help find the displacement and velocity of an object depending on how much force there is on each direction. Shoutout to Sir Isaac Newton for figuring this out. A. REAL. ONE.

2. The SI unit for force is generally NEWTONS. There are smaller sub-units to force, but are generally less used. They are hertz !!

3. An example of a force diagram with a net force of zero can be when someone pushes a huge box at 10 N and someone on the other side pushes it with the same force. The box would have to be on a flat surface so there are no force other ways. For it to be uneven, one person would have to go at 10 N and someone else at 11 N. The direction pushed with more force is where the box would go.

4. In the theme song to Bill Nye the Science Guy, it said that inertia is a property of matter. In physics, inertia is where matter exists in its resting state or in a uniform state. 

5. Isaac Newton was this super smart scientist who lived in the 1600s and 1700s. He was an influential scientist and mathematician. He came up with a bunch of scientific LAWS, meaning that they are proven and held as true.

6. His first law: An object at rest stays in rest. It also states that a motion will continue to stay in motion when moving UNLESS another force acts upon it, like gravity.
His second law: The velocity of an object changes when it is subjected to an external force. EXAMPLE: Gravity will change the velocity of an object.
His third law: Referenced in smash musical Hamilton, for every action there is an equal and opposite reaction. You can see this in force charts, where there's an equal force for every force.

7. Equilibrium is when an object is in a state where the forces and their opposite forces are balanced out. There is no force acting on an object that is stronger or weaker than the other(s).

8.  The force of the book is 1.6 N, and the mass is 2200 g. Because force = mass x acceleration, we can plug in what we know, making it 1.6 = 2200 x acceleration. The acceleration is 7.2 x 10^-4 m/s^2 !!

9. Same thing with #8. F = M x A, or 13.5 = M x 6.5, which means the mass is 2.077 g.

10. Forces always act in pairs because of Newton's third law. There has to be a second reaction.

11. Weight is relative depending on where you are. However mass is constant, based on the amount of matter you possess.

12. A normal force is a support force on an object that is in contact with another stable object. This can be something acting upwards on a table to support the things on top of the table.

13. Frictional force is proportional to normal force because the friction shown deals with how much contact an object has with the object it is on.

14. Static friction forces from two forces allows motion. This necessitates a kinetic coefficient. There is also a stationary friction which is calculated by the static coefficient and related to normal force.]]> 2017-10-13 20:55:08 UTC https://padlet.com/tec430/nqufkyol87ek/wish/196972449 Rodas Wodaj https://padlet.com/tec430/nqufkyol87ek/wish/196972482 1.

6. Newtons first Law of Motion:
An object at rest tends to stay as rest. An object in motion tends to stay in motion in a constant speed until another force acts on the object.
Newtons second Law of Motion:
How fast an object picks up speed as acceleration or slows down as deceleration depending on the amount of force used and on its mass.
Newtons third Law of Motion:

9. F=M(A) equals 13.5 Newton=6.5m/M(s)
M=13.5/6.5 =2.077 kg
10. Force always acts in pair based on Newtons third state of law. The third law states that forces always come in action-reaction pairs.
 
11. Mass is the amount of matter in an object, while weight is a measurement of force depending on gravity which is measured in Newtons. 
12. A normal force is where a bottom object pushes upward on top object. 
13. Normal forces are always perpendicular to surfaces and frictional forces act parallel to surfaces. 
14. Static friction forces allow for the sliding of two forces through the involvement of a kinetic coefficient which allows for the occurrence of motion. It is also the friction that exists due to the stationary object and the surface that is resting. ]]> 2017-10-13 20:55:24 UTC https://padlet.com/tec430/nqufkyol87ek/wish/196972482 Neha and Indira https://padlet.com/tec430/nqufkyol87ek/wish/196972520 1.

4. Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.   Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
5. Isaac Newton  was an English mathematician, astronomer, and physicist who helped develop the calculus and the theory of gravity. He lived in the 17th and 18th centuries. His background was in mathematics.
6. His first law is an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. His second law is Force= mass*acceleration.

10. Forces always act in pairs . According to Newton's 3rd law, forces come in action-reaction pairs. There must be an opposing, limiting force because otherwise, the unopposed force would move an object forever, similar to a moving object in a vacuum.
11. Mass is how much matter an object contains, and weight is the measure of gravity on mass. Weight can change if you're on the moon, but mass wouldn't change.
12.  The normal force is the support force exerted upon an object that is in contact with another stable object.
13. Frictional force is proportional to normal force because they are opposite forces. The more friction between an object and the surface, the greater the normal force that pushes back from the surface is.
14. The kinetic coefficient is the ratio of force of friction to the normal force.  A coefficient of friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are available.  Frictional force is given by Ff = μ Fn .

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.second law.
 Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Acceleration is the derivative of velocity, which is the derivative of displacement.When force is put upon an object, displacement is the change in movement that occurs. 
2) The SI Unit for force is Newtons. The smaller, sub units associated with force is kilograms. 
3) LOOK BELOW
4) The tendency to resist changes in their state of motion is described as inertia. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
5) Isaac Newton (January 4, 1643 to March 31, 1727) was a physicist and mathematician who developed the principles of modern physics, including the laws of motion, and is credited as one of the great minds of the 17th century Scientific Revolution. Isaac Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England. 
6) Newton's first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The second law is that the acceleration of an object is dependent upon two variables (the net force acting upon the object). Newton's third law states that for every action, there is an equal and opposite reaction. 
7) Equilibrium is when an object is in a state where the forces and their opposite forces are balanced out. There is no force acting on an object that is stronger or weaker than the others. 
8) The force of the book is 1.6 N, and the mass is 2200g. Force=Mass x Acceleration
We can plug in 1.6N and 2200g
1.6 = 2200x
The acceleration is 0.72 m/s^2
9) 13.5 N = Mass (6.5 m/s^2)
13.5 kgm/s^2 = Mass (6.5m/s^2)
Mass = 2.077 kg
10) Forces always act in pairs because of Newton's Third Law which states that there are always "action-reaction force pairs". This is because the force is exerted on two different objects and based on prospective the force occurs on two different objects.

12) Normal force is the support force exerted on an object in contact with another stable object. 
13) Frictional force proportional to Normal force because they are opposite. The more friction between an object and the surface, the greater the normal force that pushes back from the surface is.

In addition, it is also defined as Mass times Acceleration. Force relates to velocity because a force is the proportional thing to change in the velocity. Force relates to displacement because there are indirectly proportional. Displacement is the distance and direction of an object. It relates to acceleration because they are directly proportional. For instance, the amount of force can either increase or decrease of the acceleration.

3) Refer to the attachment at the end of this column. 
4) Inertia is the property of an object that resists change in it's motion.  In addition, it is the product of velocity and mass. Mass is a measure of this because it's quantity depends upon inertia. For instance, the mass that is large will result a greater inertia.
5) Issac Newton was a British physicist and mathematician. Created laws of his own. Also he contributed to the creation of Calculus. In addition, he lived in England. 
6) Newton's First Law states that the object will be at rest unless impacted by the external force. Newton's Second Law states that the velocity of an object is altered by an external force. Newton's Third Law states that every action has a opposite and equal reaction.
