Explain how energy is transformed when a ball is thrown into the air and then falls back to the ground.
The ball gains kinetic energy as it rises and loses potential energy as it falls.
The ball gains potential energy as it rises and gains kinetic energy as it falls.
The ball loses both kinetic and potential energy as it rises and falls.
The ball gains both kinetic and potential energy as it rises and falls.

Which of the three springs represents increased potential energy?
The compressed spring only because potential energy is only gained when an object is squeezed.
The stretched spring only because potential energy is only gained when an object is stretched out.
The compressed and stretched spring both have elastic potential energy gained from being squeezed or stretched.
none of the springs possesses potential energy
How does a pole vault pole propel the athlete over the bar?
The running athlete converts chemical PE in its muscles into KE when the pole touches the ground.
The bent pole stores KE that is converted to PE when it straightens out, propelling the athlete into the air.
The bent pole stores PE that is converted to KE when it straightens out, propelling the athlete into the air.
The athletes speed is converted to KE that propels the athlete over the bar.
In photosynthesis, what type of energy is converted into chemical energy?
Electrical energy
Kinetic energy
Solar energy
Thermal energy
A teacher rubbed a match against a piece of sandpaper. The match started to burn. Which statement best describes the energy changes that occurred?
The chemical energy stored in the match changed to thermal energy and light energy.
The thermal energy stored in the match changed to light energy and chemical energy.
The light energy and thermal energy stored in the match changed to mechanical energy.
The light energy and thermal energy stored in the match changed to chemical energy.
Which of the following statements most accurately describes how a ipod is able to play music after it has been plugged in?
The ipod is able to play music because it is using up the electrical energy from the wall.
The electrical energy is transferred from the wall allowing the ipod to make sound energy as music.
The ipod is able to play music because the outlet is creating electrical energy that is transformed to sound energy.
The electrical energy from the outlet is transformed to chemical energy and then to sound and light energy when the ipod is used to play music.
The hand generator works by turning the handle which lights up the bulb. What energy transformation occurs as the handle is turned?
Thermal to electrical
Electrical to mechanical
Mechanical to electrical to light
