The energy of a moving object is

• kinetic

• potential energy

• chemical energy

• nuclear energy

If the speed of an object doubles, its kinetic energy

• doubles

• quadruples

• stays the same

• is halved

An example of an object having elastic potential energy is

• a stretched spring

• books on a shelf

• a moving arrow

• a falling oyster

Energy stored in the bonds between atoms is called

• kinetic energy

• mechanical energy

• chemical energy

• thermal energy

The law of conservation of energy states that

• energy cannot be converted from one form to another

• energy cannot be created or destroyed

• energy resources must be used efficiently

• energy is constantly being lost to friction
