Introduction to 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

Which has more potential energy: campfire wood prior to burning or coals after a bonfire?

Back

Campfire wood prior to burning has more potential energy because it contains stored energy that can be released during combustion.

Front

What type of potential energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy, which is stored energy due to its deformation.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy.

Front

Where is gravitational potential energy at its minimum?

Back

Gravitational potential energy is at its minimum when an object is at the lowest point, such as down in the basement.

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 energy converted from potential to kinetic?

Back

Energy is converted from potential to kinetic when an object moves from a higher position to a lower position, such as a falling ball.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of chemical potential energy?

Back

An example of chemical potential energy is the energy stored in food or fuel, which can be released during chemical reactions.

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.
