Energy Transformations

Front

What is energy transformation?

Back

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

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. For example, a rollercoaster at the top of a hill has potential energy.

Front

Where is maximum kinetic energy found on a rollercoaster?

Back

At the bottom of a big hill.

Front

What type of energy transformation occurs in a hairdryer?

Back

Electrical energy is transformed into thermal energy.

Front

What type of energy transformation do wind turbines perform?

Back

Wind turbines transform mechanical energy from the wind into electrical energy.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Which device transforms electrical energy into mechanical energy?

Back

A fan transforms electrical energy into mechanical energy.

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.

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.
