ENERGY Ch.5 TEST

The energy associated with motion is called

• elastic potential
• nuclear energy
• kinetic energy
• gravitational potential energy

Kinetic energy increases as

• mass increases and velocity decreases
• both mass and velocity increase
• both mass and velocity decrease
• mass decreases and velocity increases

Which is an example of kinetic energy?

• a car waiting at a red light
• a rock poised for a fall
• an archer's bow that is drawn back
• a rolling bowling ball

Visible light is an example of

• electromagnetic energy
• chemical energy
• electrical energy
• nuclear energy

Energy is measured in units called

• pounds
• meters
• horsepower
• joules

Energy stored in the nucleus of an atom is called

• chemical energy
• electromagnetic energy
• mechanical energy
• nuclear energy

The law of conservation of energy states that when one form of energy is converted into another,

• energy is destroyed in the process
• no energy is destroyed in the process
• energy is created in the process
• some amount of energy cannot be accounted for

A change from one form of energy into another is called

• gravitational potential energy
• work
• an energy transformation
• conservation of energy

An example of something that stores chemical energy is

• light
• a match
• a microwave
• lightning

When you rub your hands together on a cold day, you use friction to convert

• nuclear energy into electrical energy
• mechanical energy into thermal energy
• electrical energy into electromagnetic energy
• thermal energy into nuclear energy
