If the box is pushed up these ramps, what will happen to the box's GPE and WHY?

• It will increase because its speed increases

• It will decreases because its speed decreases

• It will increase because its height above the floor increases

• It will decreases because its height above the floor increases

If friction is added to a system, what happens to the Mechanical Energy as motion occurs?

• It stays the same. Mechanical energy is not affected by friction

• It increases. Friction CREATES energy

• It decreases. Friction DESTROYS energy

• It decreases. Friction transforms ME to TE and/or SOUND

How would you describe the position of a pendulum bob when its energy graph looks as it does in the image?

• The bob is pulled all the way to the top of the pendulum and is at rest

• The bob is traveling somewhere between 90 degrees and 0 degrees.

• The bob is swinging past 0 degrees (the lowest point on the pendulum)
