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.
