Kinetic Energy and Work


Work Increase the kinetic energy of the object. Similarly, if you  decelerate the object  to a lesser speed by applying a force, you decrease the kinetic  energy of the object. We account for these changes in kinetic energy by saying that your force has transferred energy the object from yourself or from the object to yourself. The term …

Energy Newton’s laws of motion allow us to analyze many kinds of motion. However, the analysis is often complicated, requiring details about the motion that we simply do not know. Here is an example: A puck is sent sliding along an inclined friction less track that includes several ups and downs (hills and valleys) of various shapes. The puck’s …
