Energy Transfers & Transformations

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

At which point on a roller coaster is gravitational potential energy at its maximum?

Back

At the highest point of the roller coaster.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

At which point on a roller coaster is kinetic energy at its maximum?

Back

At the lowest point of the roller coaster.

Front

What is energy transformation?

Back

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

Front

Give an example of energy transformation from electrical to mechanical.

Back

A fan converts electrical energy into mechanical energy.

Front

What types of energy does the sun provide for solar power?

Back

The sun provides heat and light energy.

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 happens to energy during a roller coaster ride?

Back

Energy is transformed between gravitational potential energy and kinetic energy as the roller coaster moves up and down.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
