Energy transformations

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

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

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

What type of energy transformation occurs when a rubber band is stretched?

Back

When a rubber band is stretched, it transforms elastic potential energy into kinetic energy when released.

Front

What energy transformation occurs in a digital music player?

Back

In a digital music player, the energy transformation is chemical to electrical to sound.

Front

At which position does a roller coaster have the most gravitational potential energy?

Back

A roller coaster has the most gravitational potential energy at the highest point of the track.

Front

What energy transformations occur in a lamp?

Back

In a lamp, the energy transformations are electrical to thermal to light.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or batteries.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard by the human ear.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.
