                3. What is chemical energy?                      7. What is electric energy?









                4. What is nuclear energy?











                  Mo8-L1: Key Concept Check

                Direction: 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 inf uences 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 f ssion.



                            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.
