Energy 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

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

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 elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

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

How does energy transformation occur in a roller coaster?

Back

In a roller coaster, energy transforms from gravitational potential energy at the highest points to kinetic energy as it descends.

Front

What is a closed system in terms of energy?

Back

A closed system is one where no energy enters or leaves the system, meaning the total energy remains constant over time.

Front

What energy transformation occurs when a rock rolls down a hill?

Back

The energy transformation is from gravitational potential energy to kinetic energy.

Front

What is the relationship between height and gravitational potential energy?

Back

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

Front

What happens to kinetic energy at the highest point of a roller coaster?

Back

At the highest point, kinetic energy is at its lowest, while gravitational potential energy is at its highest.
