newtons law of motion are of three type . they are:

newtons first law of motion
it means that when an object is in rest or motion it tries to be in rest or motion unless the any extern al force not act on it.

newtons second law of motion.
the rate of change of momentum of an object is proportional to the applied unbalance force in the direction of the force.

newtons third law of motion.
to every action , there is an equal and opposite reaction and they act on two different bodies.

Newton gave three laws of motion that describe the motion of bodies. These laws are known as Newton's Laws of motion.

Newton First law :-
According to the law, any object in the universe remains in its state of rest or uniform motion.Inertia is of three types, namely Inertia of rest, Inertia of motion and Inertia of direction. Mass of an object is an intrinsic property of matter.

Mass is a measure of inertia of an object. If an object does not change its position with respect to time and the surroundings, it is said to be at rest and else it is said to be in motion. The rate of change in displacement of an object is called velocity. If an object covers equal displacements in equal intervals of time, the motion is called uniform motion, else it is non-uniform motion.

Mass and Inertia
According to Newton’s first law of motion, inertia is the natural tendency of an object to resist any change in its natural state of motion.Inertia of an object is not a physical quantity, and hence, we can’t measure it directly.

Newton Second law :-

An object in motion has momentum. Momentum is defined as the product of mass and velocity of an object.

The momentum of the object at the starting of the time interval is called the initial momentum and the momentum of the object at the end of the time interval is called the final momentum. The rate of change of momentum of an object is directly proportional to the applied force.
Newton's second law quantifies the force on an object. The magnitude of force is given by the equation,
F = ma, where 'm' is the mass of the object and 'a' is its acceleration. The CGS unit of force is dyne and the SI unit is newton (N).

A large amount of force acting on an object for a short interval of time is called impulse or impulsive force. Numerically impulse is the product of force and time. Impulse of an object is equal to the change in momentum of the object.

Netwon third law:-

According to Newton's third law...
For every action there is an equal and opposite re-action.
