Energy Transformations

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

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

Front

Which has more kinetic energy: a moving car or a parked car?

Back

A moving car has more kinetic energy because it is in motion, while a parked car has no kinetic 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, as it converts potential energy 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

Give an example of energy transformation.

Back

When a light bulb is turned on, electrical energy is transformed into light energy and thermal energy.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy due to its deformation.

Front

How does energy transfer when a ball is thrown up?

Back

As the ball is thrown up, kinetic energy is converted into potential energy until it reaches its highest point.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work.

Front

What is an example of an object with high potential energy?

Back

A book on a high shelf has high potential energy due to its elevated position.
