Learning Objective

In this lesson we will learn what energy is and look at the two main categories of energy. We will also learn how energy can move between objects and be converted into different forms.

Learning Outcomes

By the end of this lesson you will be able to:

• Define ‘energy’.

• Name the units for measuring energy.

• Differentiate between kinetic energy and potential energy.

• Describe the total energy of an object.

• Differentiate between energy transfer and energy transformation.

• Describe the law of conservation of energy.

• Explain why energy transfers and transformations are not 100% efficient.
