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

Where is potential energy highest on a rollercoaster?

Back

At the top of the big hill, where the car stops for a brief moment.

Front

What type of energy is chemical energy?

Back

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

Front

What energy transformation occurs in a battery-operated radio?

Back

Chemical energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What happens to energy when a hawk eats a mouse?

Back

The chemical energy from the mouse is transformed into mechanical energy for flying.

Front

What is an example of energy transformation in a rollercoaster?

Back

As the rollercoaster climbs, kinetic energy is transformed into potential energy. As it descends, potential energy is transformed back into kinetic energy.

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 is represented in a stretched rubber band?

Back

The stretched rubber band has elastic potential energy due to its position.

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.
