This principle, and the conservation of momentum, together form the cornerstone of physics at all levels. In collisions, both conservation principles must apply, but while the momentum of the system after ...

Forces and Motion
... A force tries to move an object in a particular direction, so they not only have a size (magnitude or strength) but a direction. The unit for force is the Newton (N). Any change in the state of motion of an object is the result of the sum of all the forces acting on it. The result, the combination o ...
