Energy Transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as potential energy to kinetic energy.

Front

What happens to potential energy as an object moves upward?

Back

Potential energy increases as the object gains height.

Front

What happens to kinetic energy as an object moves downward?

Back

Kinetic energy increases as the object loses height.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Define potential energy.

Back

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

Front

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

Back

As a pendulum swings, kinetic energy is highest at the lowest point, while potential energy is highest at the highest points.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.

Front

What type of energy does a book on a shelf have?

Back

A book on a shelf has potential energy.

Front

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.

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

Back

As a roller coaster climbs, kinetic energy is transformed into potential energy; as it descends, potential energy is transformed back into kinetic energy.
