Energy

The energy associated with motion is called

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

Unlike kinetic energy, potential energy is

• energy of motion
• stored
• conserved
• not measured

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

Which of the following has kinetic energy?

• a rock poised for a fall
• a stretched rubber band
• a rolling bowling ball
• a car waiting at a red light

Two objects with different masses are placed on the same shelf. Which object contains more energy?

• The object with a greater mass has more energy.
• The object with less mass has more energy.
• Both objects have the same amount of energy.
• Neither object has any energybecause they are not moving

Sound, heat, falling things and electricity are all forms of _____.

• matter
• energy

Energy _____ be changed from one form to another.

• can
• cannot

The faster an object moves, the ________ kinetic energy it has. 

• more
• less
• none of the above
• all of the above 

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy? 

• Both the potential energy and kinetic energy decrease
• The potential energy decreases while the kinetic energy increases 
• The kinetic energy decreases while the potential energy increases 
• Both the potential energy and kinetic energy increase
