Potential Energy

Poll

Grade 7 is learning about energy in class with Mr. Omar. They see the ball sitting on a table. As a student in grade 7, what do you think?

• I think the ball has no energy because it is not moving

• I think the ball has no energy because no forces are acting on it

• I think the ball has energy but less energy than if it was sitting on the ground because it is farther away from Earth's surface

• I think the ball has energy but more energy than if it was sitting on the ground because it is farther away from Earth's surface

What do we mean by potential energy?
