Energy Transformations

Identify the energy transformations:

A battery is placed in a flashlight, which completes a circuit, then produces light when turned to the on position.

• Electrical -> Elastic -> Radiant

• Chemical -> Electrical -> Radiant

• Mechanical -> Radiant -> Electrical

• Radiant -> Mechanical -> Thermal

Why does Student B have more potential energy than Student A?

• The potential and kinetic energy is always the same.

• The higher the object, the less potential energy it has.

• The potential energy never changes

• The higher the object, the more potential energy it has.

  The higher the object, the more potential energy it has.

Based on the image below, which of the following orders the points in order of decreasing potential energy?

• D, B, E, C, A

• D, B, E, C, A

• A, C, E, B, D

• C, A, E, D, B
