Newton's Laws of Motion

Define Newton's first, second and third Law of Motion? What is the difference between them?

 
Following are the Newton's three laws of motion:

1. Newton's first law of motion. It states that everybody continues in the state of rest or of uniform Motion; in a Straight line, unless it is acted upon by some external force.

2. Newton's second law of Motion. It states that the rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts.

3. Newton's third law of motion. It states that to every action, there is always an equal and opposite reaction.
