Energy 2 NBE

A battery converts what type of energy to another?

• sound to kinetic
• light to heat
• mechanical to electrical
• chemical to electrical

On a roller coaster, where is maximum potential energy?

• At the bottom of a big hill
• When going around a corner
• When going upside down
• At the top of a big hill

Energy that is transferred by objects touching is called?

• Conduction
• Convection
• Induction
• Radiation

The ultimate source of energy is:

• The sky
• The sun
• Plants
• Movement

Energy can be classified into two main categories, kinetic energy and potential energy.  Kinetic energy is when an object is:

• standing still
• actively doing something
• changing states of matter
• objects do not have kinetic energy

When a hot object touches a cooler object, heat energy is transferred from the warmer object to the cooler object through:

• radiation
• electrical energy
• conduction
• solar heating

You and your family are sitting around a campfire.  You can feel the heat on your face, even when you back your seat away from the fire.  The heat energy from the fire warms your face through:

• light energy from the fire
• conduction
• chemical reactions in the fire
• radiation

Which is an example of potential energy?

• a roller coaster speeding down a hill
• the pulled back string on an archers's bow
• releasing the strings on a guitar
• an electric current lighting a light bulb

Which of the following is an example of potential energy?

• a ball rolling down a ramp
• a stretched rubber band
• a baseball flying into the outfield
• a snail moving across a rock

Gasoline that powers a car is an example of...

• Nuclear energy
• Chemical energy
• Sound energy
• Light energy
