Key Concept How do potential energy and kinetic energy differ?
Directions: On the line before each statement, write T if the statement is true or F if the statement is false. If the
statement is false, change the underlined word(s) to make it true. Write your changes on the lines provided.
1. Energy is the ability to cause change and influences almost everything in life.
2. The stored energy between atoms, ions, and molecules is kinetic energy.
3. When volume or height increases, gravitational potential energy increases.
4. Energy that depends on particle types, positions, attractions, and repulsions
among a group of particles is termed nuclear energy.
5. All atoms are joined by chemical bonds.
6. Large amounts of energy are released when the nuclei of atoms join together in
a process called nuclear fission.
7. All objects that have gravity have kinetic energy.
8. An object that has a greater mass and density has a greater kinetic energy than
an object that has less of each.
9. Electrons in an atom move around the nucleus.
10. Potential energy and electric energy can combine to form a system.
11. Everything that is not part of a system is part of gravitational potential energy.
12. The nerves in your body that send signals from your arm to your brain use
electric energy.
13. The food you eat provides your body with nuclear energy.
