Potential & Kinetic Energies Nine Week Review

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

When does an object have the greatest kinetic energy?

Back

An object has the greatest kinetic energy when it is moving at its highest speed.

Front

What type of energy does a skateboarder have at the top of a ramp?

Back

Gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What type of wave is a sound wave?

Back

Sound waves are longitudinal waves.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases.

Front

What is an example of elastic potential energy?

Back

A stretched rubber band or a compressed spring.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest points of swing, while kinetic energy is highest at the lowest point.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula is PE = mgh, where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height.
