Forms of Energy

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 is gravitational potential energy at its maximum for a pole vaulter?

Back

Gravitational potential energy is at its maximum just before the pole vaulter starts to fall to the ground.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only converted from one form to another.

Front

What type of energy does a microwave oven convert?

Back

A microwave oven converts electrical energy to thermal energy.

Front

What happens to potential energy as an object falls?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

How is potential energy related to height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the formula for gravitational potential energy?

Back

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

Front

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

Back

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

Front

What is an example of energy conversion in a roller coaster?

Back

In a roller coaster, potential energy is converted to kinetic energy as the coaster descends from a height.
