### Newton's Law of motion

Sir Isaac Newton's express idea of motion in the frame of 3 laws, which are known as law of  motion.

• Law of Inertia
• Law of Force or Momentum
• Law of Action and Reaction

### Law of Inertia :

That properties of a body is can not change it state of rest or uniform motion is called "inertia" and the influance under which the vilocity of particle change is called force.
The law of inertia it state as "A body continues in it state of rest or uniform motion unless not disturbed by same external influence of the force.

### Law of Force or Momentum :

Everybody changes to the state of rest or uniform motion of body when a net internal force acts on the body.
This law states the rate of change of momentum of a body is directly propotional to impressed force and the change takes place in the direction of the force.
or
The rate of change of lonear momentum is directly propotional to the product of mass and acceleretion.
If  vector F is the force and vector P is the instataneas momentum at time t.

### Law of Action and Reaction :

Newton's 3rd law states that "To every action there is always and equal and opposite reaction but action and reaction forces is acts on different bpdy".
Cosider two body 1 and 2, the body 1 exerts force on body 2 denoted by vector F21 and another body 2 exerts of force on a body 1 denoted by vector F12 then accotding to Newton's 3rd law-
