Conservation of Energy
Printer Friendly Version
Refer to the following information for the next four questions.
A ball gains 30 J of potential energy when lifted to the top of a vertical post.
How much potential energy will it gain if rolled to the top of an incline that is the same height as the post?
If the ramp is then subdivided into three equally spaced steps, how much potential energy will it have on the second step?
On the third step?
If the ball where to fall off the back of the platform, how much kinetic energy would it have when it strikes the ground?
A massive steel container in initially lifted to a position directly above a post that needs to be driven into the ground.
According to the picture, when the rope is cut, how much work will the steel container do on the post when they collide?
A pendulum is initially displaced to a height

where it has 10 J of potential energy. After it is released, specify the amount of kinetic energy that it will have at each of the following positions in its swing.
