Practical - Force and Acceleration

Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...

In this video Paul Andersen explains how contact forces result from interatomic forces. The following forces are explained at the interatomic level: normal force, applied force, friction force, tension force, spring force, and buoyant...
