Almost all types of energy can be classified as either kinetic energy or potential energy. The ( kinetic or potential) energy of a racehorse is what you see when the horse runs around the track.
Kinetic
The (Celsius or Fahrenheit or Kelvin) scale is used for everyday purposes in most nations and in science.
Celsius
The wavelength is the distance between two consecutive (crests / amplitudes / resting points) of a wave.
crests
The horse has this type of energy because it is (storing energy or moving).
Moving
People in the United States use the (Celsius or Fahrenheit or Kelvin) scale for weather and cooking temperatures.
Fahrenheit
The amplitude is the distance between the crest and the (resting point/ end point / trough) of a wave.
resting point

D. A skydiver jumping out of a plane
D. A skydiver jumping out of a plane

Two beakers are filled with different substances, but at the same temperature. The particles of substance A are more massive than those of substance B.Which particles are moving faster, and how can you tell?
A. The particles in A and B have the same average speed, since they are at the same temperature.
B. The particles in beaker A have a higher average speed than those in B, because their higher mass makes them harder to stop.
C. The particles in beaker B have a higher average speed than those in A, because their lower mass makes them move faster.
D. The particles in beaker B must be moving faster to compensate for their lower mass and still have the same average kinetic energy as those in A.
D. The particles in beaker B must be moving faster to compensate for their lower mass and still have the same average kinetic energy as those in A.
Zhang throws a small rock and a big rock into a lake and notices the different waves that form on the water’s surface. The big rock made taller waves but the distance between the waves was the same as the little rocks. What did an increase in the size of the rock change about the wave?
A. It made the wavelength shorter but did not change the amplitude.
B. It made the wavelength longer but did not change the amplitude.
C. It made the amplitude smaller but did not change the wavelength.
D. It made the amplitude bigger but did not change the wavelength.
D. It made the amplitude bigger but did not change the wavelength.
