Using energy review

Sound, light, heat and moving objets are all examples of

• energy

• matter

• electricity

• motion

The faster an object is moving

• the quicker it will stop

• the more energy it possesses

• the less energy it has

• the greater the mass

When objects collide

• they may make a noise

• energy can be transferred

• one or more objects may change direction

• All of these things could happen

Devices can be designed to

• destroy energy

• create energy

• convert energy from one form to another

• create and destroy energy

A complete electrical circuit using a battery to power a clock is an example of converting

• chemical energy to electrical energy

• light energy to heat energy

• kinetic energy to light energy

• heat energy to motion energy

A ball resing on the top of a hill has

• kinetic energy

• potential energy

• light energy

• no energy

Energy can be transferred from place to place by

• light

• sound

• heat

• all of the above

Which of the following statements about energy are true?

• You can create energy by rubbing your hands together

• you can destroy energy by submerging it in water

• Energy cannot be created

• Energy cannot be transferred

When objects collide

• Energy is reflected by the moving objects

• Energy is canceled by the opposite force

• The two objects have no reaction

• Energy is transferred from one object to another

An object that is going fast has

• more energy

• less energy

• more friction

• less gravity
