Newton's Firts law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
e.g...ball, door, and a rocket etc.
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
e.g......a car, more than forces are applied.
Newton's third law is for every action, there is an equal and opposite reaction.
e.g......... a shooting gun, a shoe and a boat.
Vilocity is a vector quantity, which is one that requires a magnitude and a direction. An example of vilocity is a car driving at 75 miles per hour.It is the rate of change of displacement.The rate of change for vilocity is acceleration.Acceleration is the rate of change of velocityAcceleration  is also a vector quantity as it is just the rate of change of vilocity.

Q3. Define simple machines with examples.
Ans: Simple machine, any of several devices with few or no moving parts that are used to modify motion and force in order to perform work.
E.g
inclined plane, lever, wedge, wheel and axle, pulley, and screw.

Q1 Newton's Three Laws of Motion. Newton's three laws of motion may be stated as follows: Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it. Force equals mass times acceleration For every action there is an equal and opposite reaction. Examples When you jump off a small rowing boat into water, you will push yourself forward towards the water
Q2.. Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity. Velocity is a vector quantity because it consists of both magnitude and direction. Acceleration is also a vector quantity as it is just the rate of change of velocity.
Q3..Simple machine, any of several devices with few or no moving parts that are used to modify motion and force in order to perform work. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

Q2. Differentiate between velocity and acceleration?
Velocity:
the speed of something in a given direction.
Acceleration:
Acceleration is a measure of how fast velocity changes.

A1:Newton’s 3 laws of motion may be stated as follows every object in a state of uniform  motion will remain in the state motion  unless an external force acts on it. Force equals mass time acceralation for every action there is an equal and opposite reaction
A2) the difference between velocity and acceleration is that velocity defines the rate with which the object varies it’s position while acceleration is defined as the rate with which the velocity of the object  changes during motion velocity is given as the ratio of change of position in time.
A3) simple machines, any of several devices with few or no moving parts that are used to modify motion and force in order to perform work , the simple machines are the inclined plane , lever, wedge , wheel and axle, pulley and screw

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.

Second law

In an inertial frame of reference, 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(It is assumed here that the mass m is constant

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.

# data[].attributes.body
In the first law an object would not change the motion until a force acts on it.in the second law the force on a object is equal to its massin the third law when 2 objects interact it appliesfirces to each other of even magnitude and opposite direction

# data[].attributes.body
First law:
The first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.The motion of a kite when the wind changes can also be described by the first law.
Second law:
Examples of Newton's 2nd Law If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one.
Third law:
Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

Q1. Write the three laws of motions with examples?
A1. Newton's laws of motion relate an object's motion to the forces acting on it.In the second law the force on an object is equal to its mass.The third law is about two objects interacting.They  apply forces to each other of equal magnitude and opposite direction.

Q2. Differentiate between velocity and acceleration?
A2. Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity.

Q3. Define simple machines with examples.
A3. Simple machine, any of several devices with few or no moving parts that are used to modify motion and force in order to perform work. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

the three laws of motion.
the first law states that an object will remain at rest or moving in a straight line unless acted upon by an external force.
example:
The motion of a ball falling down through the atmosphere.     SECOND LAW
the second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.
example
Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force
THIRD LAW
every action has an equal and opposite reaction.
example
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

Madina:
1st law : every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
E.g
A book placed on a table will stay at its place unless someone or something comes and apply force on it and moves it moves.
2nd Law: Force is equal to the change in momentum per change in time.
E.g
If a stronger player hits a ball with more force it will go further and faster then the player who is weak and did not hit the ball with a lot of force who’s ball will not go far.
3rd Law:
For every action there is an equal and opposite reaction.
E.g
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
