... due to gravity is perpendicular to the direction of motion. This means the work done is zero. Hence, there is no change in kinetic energy of the planet, so it does not speed up or slow down. This is true for a circular orbit. 51. Claw Hammer A claw hammer is used to pull a nail from a piece of wood, ...

... relative motion of an object. If you slide a hockey puck across a wooden floor, it slows down and stops because friction resists its motion. If you slide the same hockey puck across ice instead of the floor, the puck slides farther before stopping because ice applies less friction on the puck than t ...

If the force acting on a particle causes it to move, then it is possible to integrate the force with respect to displacement instead of time, and this results in a va ...
