Energy transformations

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from electrical energy to mechanical energy.

Front

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

Back

Potential energy.

Front

How can you increase the potential energy of an object?

Back

By raising the object higher above the ground.

Front

What energy transformation occurs when a flashlight shines?

Back

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

Front

Which position has the least amount of potential energy?

Back

The position closest to the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

Give an example of a device that transforms electrical energy into mechanical energy.

Back

A fan is an example of a device that transforms electrical energy into mechanical energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases as the height of an object increases.

Front

What type of energy transformation occurs in a battery-powered toy?

Back

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