Newtons laws of motion or Newtons first-second-third law

Explain Newtons laws of motion or Newtons first law, second law and third law of motion?

Newton's laws of motion (Sir I. Newton)

Newton's first law of motion:

The body continues in its state of constant (steady) velocity (which might be zero) unless it is acted on by an external force.

Newton's second law of motion:

For unbalanced force executing on a body, the acceleration generated is proportional to the force impressed; and constant of proportionality is the inertial mass of the body.

Newton's third law of motion:

In a system where no external forces are existed, in every action the force is always opposed by an equivalent and opposite reaction force.
