Unit 3 LS 1-2 Quiz

Objects may have potential energy or kinetic energy. How do potential energy and kinetic energy compare to each other?

• An increase in one leads to an increase in the other.

• Both describe objects in motion

• Both describe objects that are at rest.

• Both are forms of mechanical energy.

Objects can have potential energy because of their position. Which object has potential energy?

• spinning wheels on a bicycle

• a book sitting on a table

• hands turning on a clock

• a flag flapping in the wind
