• energy is not created or destroyed and its form is constant

• energy cannot be created or destroyed

• when energy is transformed, the total energy of a system is less than it was before the change

• energy can be created and destroyed but cannot change form

9

• The kinetic energy and potential energy both remain constant.

• The kinetic energy decreases, and the potential energy increases.

• The potential energy decreases, and the kinetic energy increases.

• Mechanical energy increases.
