Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

Which object has kinetic energy?

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of an object.

Front

When is potential energy greatest in a pendulum?

Back

Potential energy is greatest at the highest points of the swing (points 1 and 5) when the pendulum is momentarily at rest.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy stored in an object due to its height above the ground.

Front

Which has more gravitational potential energy: a minicooper or a semi truck?

Back

A semi truck has greater gravitational potential energy due to its larger mass.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to kinetic energy when speed doubles?

Back

If the speed of an object doubles, its kinetic energy increases by a factor of four.

Front

What is the relationship between height and potential energy?

Back

As the height of an object increases, its gravitational potential energy also increases.

Front

What is an example of potential energy?

Back

A car parked on a steep hill has gravitational potential energy due to its height.
