Multiple Choice

Which of the following best illustrates the physics definition of energy?

• "The height of her jumps takes more energy than anyone else's."

• "I don't have the energy to get that done today."

• "Our team needs to be at maximum energy to win the game."

• "The show was so exciting you could feel the energy in the audience."

Multiple Choice

Which statement below provides a correct practical definition of energy?

• Energy is a quantity that can be created or destroyed.

• Energy measures how much $ it takes to produce a product.

• The energy of a product can never change. It depends on size and weight.

• Energy causes matter to change and determines how change occurs.

​Final thoughts . . .

Without energy, nothing can change --- not speed, temperature, or even color. Understanding the flow of energy through matter opens a window into understanding how things work.
