Energy

Energy can be converted from one form to another

• True

• False

The energy of a moving object is

• kinetic energy

• 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 fallind oyster

An example of electromagnetic energy is

• a falling rock

• a stretched spring

• a speeding train

• sunlight

Energy stored in the bonds between atoms is called

• kinetic energy

• mechanical energy

• chemical energy

• thermal energy

Mechanical energy is

• found in machinery only

• usually measured at the atomic level

• the sum of the chemical and thermal energy of an object

• the sum of the kinetic and potential energy of an object

An example of the conversion of gravitational potential energy into kinetic energy is

• a falling raindrop

• a gasoline-powered engine

• striking a match

• a hockey puck sliding on ice

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
