Back

C

Front

What is kinetic energy?

Back

The energy that an object has due to its motion.

Front

Which passenger has the most potential energy?

Back

D

Front

Which of the following has the most kinetic energy? A car traveling at 80 kph., A tractor-trailer traveling at 80 kph., A cheetah running at 80 kph., A motorcycle traveling at 80 kph.

Back

A tractor-trailer traveling at 80 kph.

Front

When does an object have no kinetic energy?

Back

When it's at rest.

Front

When is potential energy transformed into kinetic energy? Options: When an object at rest is lifted to a higher elevation., When an object at rest remains at rest., When an object at rest is put into motion., When an object in motion is stopped and out at rest.

Back

When an object at rest is put into motion.

Front

The slower an object moves, the ______________ kinetic energy it has.

Back

Less

Front

Why do objects at high elevations have more potential energy than objects at low elevations?

Back

Because gravity gives objects at high elevations the potential to fall much further.
