... (2) The work done by a C.F. depends only on the start and end position of the object (being worked on), not the path from start to finish. Give two examples of conservative forces. Force of gravity AND Force of a spring The work done by gravity/spring is the EXACT SAME as the potential energy equati ...

... Circular motion is rotation along a circle: a circular path or a circular orbit. It can be uniform, that is, with constant angular rate of rotation, or non-uniform, that is, with a changing rate of rotation. Examples of circular motion are: an artificial satellite orbiting the Earth in geosynchronou ...

... and the Normal Force An object at rest must have no net force on it. If it is sitting on a table, the force of gravity is still there; what other force is there? The force exerted perpendicular to a surface is called the normal force. It is exactly as large as needed to balance the force from the ob ...
