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 is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as an object at a height or a compressed spring.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

How does energy transform in a roller coaster?

Back

As a roller coaster climbs, potential energy increases; as it descends, potential energy is converted into kinetic energy.

Front

What happens to energy when a hot plate is turned on?

Back

Electrical energy is transformed into thermal energy, which heats the plate.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

Front

What is an example of energy transfer as heat?

Back

When warm water from a stream flows into a cooler lake, the stream water transfers heat to the lake water.

Front

What cannot happen to energy according to the Law of Conservation of Energy?

Back

Energy cannot be created.

Front

What is an example of potential energy being converted to kinetic energy?

Back

A skier at the top of a hill has potential energy that converts to kinetic energy as she descends.

Front

What is the relationship between potential energy and height?

Back

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