Newton’s Laws of Motion
A force is a "push" or "pull" experienced by a mass m when it is accelerated.
1. Body at rest remains at rest and a body in motion continues to move at a constant
velocity unless acted upon by an external force
2. A force F acting on a body gives it an acceleration “a” which is in the direction of the
force and has magnitude inversely proportional to the mass “m” of the body. F = ma.
3. To every action there is an equal and opposite reaction.
