# What are the laws of motion?

#### Newton’s laws of motion

Newton’s gives three law of motion:

##### 1. Newton’s first law motion

A body continues in its state of rest or constant velocity along the same straight line, unless not disturbed by some external force. This is Newton’s first law motion.

##### 2. Newton’s second law motion

Time-rate of change of momentum is proportional to the applied external force. This is Newton’s second law motion

##### 3. Newton’s third law motion

To every action there is always equal and opposite reaction. This is Newton’s third law motion.
