How it works
This kinetic and potential energy worksheet prints ten everyday examples, such as a rolling bowling ball, a stretched rubber band and a new battery, above two headings: Kinetic energy and Potential energy. Pupils write each one under its heading. A key is the last page.

Where each is greatest on a hill and on a swing
A roller coaster car has the most potential energy at the top of its highest hill and the most kinetic energy at the bottom, where it is fastest. A swing behaves like a pendulum: potential energy is greatest at the two ends of the arc, where the swing stops for an instant, and kinetic energy is greatest at the lowest point.
- Nothing on the sheet is both moving and high up, so every example has one answer.
Questions and answers
What is the difference between kinetic and potential energy?
Kinetic energy is the energy of motion: anything that moves has it, and more of it the faster it goes. Potential energy is stored energy, held in an object's height, in a stretch or a squeeze, or in a fuel, a food or a battery.
What are the types of potential energy?
The list under the tool has three. Gravitational potential energy comes from height. Elastic potential energy is stored in something stretched, squeezed or bent. Chemical potential energy is stored in fuels, food and batteries. A fourth kind, nuclear, is held in the nuclei of atoms.
Can an object have kinetic and potential energy at the same time?
Yes. A roller coaster car halfway down a hill is moving and is still above the ground, so it has both. As it drops, potential energy turns into kinetic energy, and their sum stays the same apart from what friction and air drag take.
Is there a kinetic and potential energy worksheet for 3rd grade, 4th grade or 5th grade?
This page serves all three: no grade is printed on the sheet, and it asks for no formula. Each example is sorted by one question: is it moving, or is it holding still with energy stored?
