Physics was Never so Easy!
Newtons Laws of Motion
Newtons first law of motion states that a body at rest will remain at rest or a
body in uniform motion along a straight line will remain in uniform motion
unless an external force is acting on it.
This means that if one rolls a ball in a vacuum with no external forces
applying on it (e.g: Gravity etc.) then it will keep on rolling for all eternity. It
also states that if the ball is put at rest in the same type of environment then it
will alway remain at rest.
This phenomenon is called Inertia!
Inertia is the inability of an object to change its state of motion by itself.

Newtons second law of motion states that the rate of change of momentum of
a body is directly proportional to the force applied and takes place in the
direction of the force.
Momentum is the total quantity of motion possessed by a moving body.
Momentum is directly proportionate to the bodys mass as well as its velocity.
p=mv
where p is momentum;
m is mass;
and v is velocity.
Also we must know about a formula which tells us how to calculate the
amount of force required to accelerate or decelerate a body according to its mass:
F=ma
Where f is force;
m is mass of the body;
and a is acceleration.

Newton third law of motion states that every action has an equal and opposite
reaction.
