Kinetic and Potential Energy

Front

What is kinetic energy?

Back

The energy that an object has due to its motion.

Front

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

Back

A tractor-trailer traveling at 80 mph.

Front

When does an object have no kinetic energy?

Back

When it is at rest.

Front

When is kinetic energy transferred from object to object?

Back

When those objects collide.

Front

Which passenger has the most potential energy? A, B, C, D.

Back

D.

Front

What is potential energy?

Back

The stored energy of an object due to its position or condition.

Front

What factors affect kinetic energy?

Back

Mass and speed of the object.

Front

How is potential energy calculated?

Back

Potential energy = mass × gravity × height.

Front

What happens to kinetic energy when an object speeds up?

Back

Kinetic energy increases.

Front

What is the relationship between kinetic and potential energy?

Back

They can be converted into each other; for example, potential energy converts to kinetic energy when an object falls.
