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 happens to energy during a transformation?

Back

During an energy transformation, energy changes from one form to another, but the total amount of energy remains constant (Law of Conservation of Energy).

Front

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What type of energy is stored in a stretched rubber band?

Back

The energy stored in a stretched rubber band is called potential energy.

Front

What type of energy is produced when a cell phone rings?

Back

The energy produced when a cell phone rings is sound energy.

Front

What is the relationship between electrical energy and thermal energy?

Back

Electrical energy can be transformed into thermal energy, as seen in devices like toasters and heaters.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.

Front

What is an example of chemical energy?

Back

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

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.
