Energy Transfer

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one place or object to another, often changing its form in the process.

Front

What type of energy do wind turbines convert?

Back

Wind turbines convert kinetic energy (from wind) into electrical energy.

Front

What type of energy does a battery convert?

Back

A battery converts chemical energy into electrical energy.

Front

Where is maximum potential energy on a roller coaster?

Back

Maximum potential energy is at the top of a big hill.

Front

What energy transfer occurs when a plant makes food from sunlight?

Back

The energy transfer is from solar energy to chemical energy.

Front

What is gravitational potential energy (GPE)?

Back

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

Front

Which has greater gravitational potential energy: a 20 kg object at 10 m or a 100 kg object at 10 m?

Back

A 100 kg object at 10 m has greater gravitational potential energy.

Front

What is kinetic energy?

Back

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

Front

How does height affect gravitational potential energy?

Back

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

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is GPE = mass (kg) × gravity (9.8 m/s²) × height (m).
