8/25 LESSON 2 Other Forms of Energy Pgs. 14-23

Multiple Choice

Why is it important to understand the different forms of energy and how they are related to each other?

• Because it helps us use energy more efficiently and safely

• Because it is required for passing exams

• Because energy is only used in science experiments

• Because it makes machines work faster

Multiple Choice
