Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What are the two main types of energy?

Back

Kinetic energy (energy of motion) and potential energy (stored energy).

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

How does potential energy change as an object falls?

Back

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

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What happens to kinetic energy when a ball is thrown upwards?

Back

Kinetic energy decreases as the ball rises and potential energy increases.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

How can you calculate gravitational potential energy?

Back

Gravitational potential energy (GPE) = mass (kg) × gravity (9.8 m/s²) × height (m).

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, potential energy transforms into kinetic energy.
