REVIEW AND SUMMARY Force And Motion

REVIEW AND SUMMARY Force And Motion Newtonian Mechanics The velocity of a particle or a particle like body can change (the particle can accelerate) when the particle is acted on by one or more forces (pushes or pulls) from other objects. Newtonian mechanics relates accelerations and forces. Force Forces are vector quantities. Their magnitudes are defined in terms of …
