... A 2 kg rock is at the edge of a cliff 20 meters above a lake. It becomes loose and falls toward the water below. Calculate its potential and kinetic energy when it is at the top and when it is halfway down. Its speed is 14 m/sec at the halfway point. You can assume the initial speed is 0 m/sec bec ...

... Therefore, if the Sun is at rest, there is no disturbance of the Newtonian law, because its "field of force" is stationary. But if it has a motion through space, there is a slight weakening of the force in the line of motion, and a slight strengthening equatorially. The direction is still radial. ...

... & Q2, imagine bringing each in from infinitely far away. • The first one takes no work, since there is no external electric field. To bring in the 2nd one, work must be done, since it is moving in the Electric Field of the first one; this means that the Electric Potential Energy U of the pair is: ...
