could you please explain newton's second law of motion?
Asked by brijmmc | 5th Oct, 2009, 11:35: AM
The second law of motion determines the effect of net force on a body.
The time rate of change of momentum of a body is equal to the net (resultant) external force acting on the body.
force = change of momentum/time = (final momentum - initial momentum)/time
Linear momentum = mass x velocity.
These expressions simplify to force = mass x acceleration.
