Energy Transformations

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 above the ground.

Front

At which position does a child on a swing have the most gravitational potential energy?

Back

At the highest point of the swing's arc.

Front

What is energy transformation?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and speed of an object.

Front

At which point does a ball have the greatest gravitational potential energy?

Back

At the highest point of its trajectory.

Front

When is kinetic energy highest in a pendulum swing?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What is an example of energy transformation in a swinging pendulum?

Back

As the pendulum swings down, gravitational potential energy is converted into kinetic energy.

Front

What happens to gravitational potential energy as an object falls?

Back

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

Front

What is the formula for calculating gravitational potential energy?

Back

GPE = mass (kg) × gravitational acceleration (9.8 m/s²) × height (m).

Front

What type of energy is stored in food?

Back

Chemical energy.
