A force is a physical power exerted on an object.
2. the SI unit for force is Newton or kg-m/s2
3. see below
4.  Inertia is the property of matter where it retains its OG state if it is not acted on by another force. Mass is a measure of inertia because mass is dependent on inertia. Mass increases with inertia.
5. Issac Newton was an English mathematician, physicist, and knight apparently. He lived the kingdom of England and then Great Britain. He was an aristocrat aka petty bourgeoisie. He was an Anglican. He was against the 3 gods concept. He shares credit with Leibniz for inventing calculus.
6. 1st law - Everything moves at a constant (non-zero) velocity, unless acted on by a force
2nd law - force is equal to the sum of the mass and acceleration of the object
3rd law - every action has a reaction
7. Equilibrium is when both forces are equal whether both are 0 or they cancel each other out. When both is 0, it is static equilibrium. When they cancel each other out, it is dynamic equilibrium.
8. F = ma
   1.6 N = 2.2 kg * a
    a = 0.7272... m/s2
9. 13.5 N = m * 6.5 m/s2
   m = 2.1 kg
10. Forces always act in pairs because when their is a pull, there is a pull.
11. Mass is the amount of matter in an object. Weight is the gravitational pull on an object.
12. a Normal force is a force that is pushed up by the ground. 
13. Frictional force is proportional to normal force because friction causes more force and that is normal for the ground
14. the kinetic coefficient is the coefficient the ratio of friction to the normal force.
the static coefficient is the product of the friction and the normal force. ]]> 2017-10-12 20:27:31 UTC https://padlet.com/tec430/nw1t5vvouq46/wish/196630749 Eric N, Stephen G. enguyen2k1 https://padlet.com/tec430/nw1t5vvouq46/wish/196630760 1.  Force is mass multiplied by acceleration. Force allows the acceleration and displacement of an object.  The velocity is essentially the force.
2. The Si unit for force is NEWTONS : kg*m/s^2
4.Inertia is when an object stays in motion or at rest until acted upon an outside force.  Inertia is dependent on mass.
5. Isaac Newton was well known for his work on gravity.  He lived in England when he was alive.  
6a. Newtons first law is that every object will stay in motion or at rest until acted upon by an outside force.  
6b. Newton's second law is when acceleration is produced when a force acts on the mass/acceleration of the object.  
6c. Newton's third law is every action has a reaction.
7. Equilibrium is when two forces are equal, in terms of 0, it's called static equilibrium.  
8. 1.6/2/2= 0.72727272727MpS^2
9. 13.5 N/6.5 m/s^2 = 2.08 kg
10. Forces always act in pairs because of Newton's third law which says that for every action there is an opposite and equal reaction.
11. Mass is the amount of matter in a certain object whereas weight is the force exerted by gravity upon an object.
12. Normal force is the force perpendicular to the surface of contact.
13. Frictional and normal forces are proportional because they act in opposite directions of each other.
14. The kinetic coefficient is the amount of energy acting on an object in motion. The static coefficient is the force whose value does not change.

A force can cause an object with mass to change its velocity. Velocity is a vector quantity and has both a magnitude and a direction. The direction is the same as the the displacement direction from which we defined the velocity. From Newton's second law of motion, we know that forces on an object produce accelerations.
2.The SI unit of force is Newton =kg*m/s^2
3.  PICTURE  VVVV
4.Inertia is the resistance of any physical object to any change in its state of motion. The more inertia an object has, the more mass that it has,so the massive the object it has a greater tendency to resist changes in its state of motion.
5. Isaac Newton is best known for his work on gravity. He also worked on and discovered many other scientific wonders during his lifetime (1642-1727). His work in physics was so advanced that he was the first scientist to be knighted.
6.Newton’s First Law of Motion: An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same directions acted upon by an unbalanced force. 
Newton’s Second Law of Motion: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Newton's Third Law of Motion: For every action there is an equal and opposite re-action.
7.If an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium." "Static" means stationary or at rest. A common physics lab is to hang an object by two or more strings and to measure the forces that are exerted at angles upon the object to support its weight.
8. f=M(a)
1.6N=(2.2kg)(m/s^2)
m/s^2=.7272
9.F=M(a)
13.5=6.5m/s^2(kg)
m=2.08kg
10. Forces always act in pairs since there always has to be in opposite direction and always in action-reactions pairs.
11. Mass is a constant for each object, meaning that the mass won't change unless the object changes.
On the other hand Weight changes due to the gravity; any object's weight is the force pulling it down to the ground. 
12. The normal force is the support force exerted upon an object that is in contact with another stable object.
13. According to the laws of physics, the force of friction, always acts to oppose the force you apply when you try to move an object. Friction is proportional to the force with which an object pushes against the surface you’re trying to slide it along.
14. Kinetic Coefficient occurs when two objects are moving relative to each other and rub together and Static Coefficients is when two or more solid objects that are not moving relative to each other.

Due to the change in motion (towards a specific direction), force has both displacement and vector quantity. If you increase the force of an objection, the acceleration increases as well.

2)N=kg*m/s^2 (N = Newton)

3)
4) Inertia is a tendency to do nothing. The more inertia an object has, the more mass it has.

5) Issac Newton (1642-1727) was an English mathematician who was known for his work on gravity. He developed three laws of motion.

6) 
!st law of motion - every object will remain at rest or in uniform motion in a straight line if no other external forces act on it.
2nd law of motion - acceleration is produced when a force acts on a mass (net force = mass*acceleration)
3rd law of motion - for every action, there is an equal and opposite reaction

7) Equilibrium is a state in which opposing forces or influences are balanced.

a = 0.727 m/s^2

9) F=ma
13.5 N = m * 6.5 m/s^2

10) Forces always act in pairs because newtons third law states that for every action and force, there is an equal and opposite reaction force.

11) Mass is the actual amount of material contained in a body, whereas weight is the force exerted by the gravity on the object.

12) Normal force is the support force exerted upon an object that is in contact with another stable object.

13) Fiction force is proportional to normal force because frictional resistance force between two surfaces is proportional to the normal force pressing them together.

14) Kinetic coefficient happens when two objects are in motion and are relative to one another. Static coefficient is when two or more solid objects that are not in motion are relative to one another.]]> 2017-10-12 20:46:15 UTC https://padlet.com/tec430/nw1t5vvouq46/wish/196635289 https://padlet.com/tec430/nw1t5vvouq46/wish/196636908 2017-10-12 20:54:03 UTC https://padlet.com/tec430/nw1t5vvouq46/wish/196636908 https://padlet.com/tec430/nw1t5vvouq46/wish/196639084 2017-10-12 21:04:06 UTC https://padlet.com/tec430/nw1t5vvouq46/wish/196639084 Laura, Emily B, Shirley https://padlet.com/tec430/nw1t5vvouq46/wish/196642962 14. The coefficient of kinetic friction is the force between two objects when one object is moving, or if two objects are moving against each other. It does not have any units. The static coefficient of friction is the ratio of the force of friction between an object and a surface to the frictional force resisting the motion of the object. It is used to find an object's normal force or frictional force. ]]> 2017-10-12 21:22:37 UTC https://padlet.com/tec430/nw1t5vvouq46/wish/196642962 Navjot https://padlet.com/tec430/nw1t5vvouq46/wish/196647518 1.  Force is an object's mass multiplied by its acceleration and causes a change in motion. Force could cause an object to change velocity, and velocity is a vector quantity that leads to net direction, or displacement. Force creates the velocity of an object and causes displacement and acceleration in that object. 
2. The SI unit for force is Newton, or N.
3. 
                                       
4. Inertia is when a property of matter remains in a state of rest or uniform motion, unless it was disturbed by an external force. Mass is the quantity that is dependent on the inertia of an object, meaning the more inertia an object has, the more mass that object has and vice versa.
5. Isaac Newton was an English astronomer, physicist, and mathematician who was considered as the most influential scientists and a key figure in the scientific revolution. He was born on January 4, 1643 and died March 31, 1727. 
6. The first law is also called the law of inertia and states that an object at rest stays at rest while an object in motion stays in motion, unless acted upon by an unbalanced force. Newton’s second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force. Newton’s third law states that for every action, there will be an equal and opposite reaction.
7. Equilibrium is a state of physical balance and results from the cancellation of forces acting on an object.
8. F=ma
1.6 N=2.2 kg a
a=0.7272 m/s2
9. F=ma
13.5 N=6.5 m/s2m
m=2.08kg
10. Forces always act in pairs due to Newton’s Third Law. 
11. Mass is the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg.
12. Normal force is the component, perpendicular to the surface.
13. The more normal force there is, the more friction there is. 
14. Kinetic coefficients affect objects in motion whereas static coefficients affect objects at rest.
