A student throws a marble using a rubber band two times. In trial 2, the rubber band is stretched farther than in trial 1. The marble in trial 2 has more energy than the marble in trial 1. What is the relationship between the stretch in the rubber band and the speed of the marble?
The stretch in the rubber band changes the mass of the marble but does not change the speed of the marble.
The stretch in the rubber band changes the distance the marble travels but does not change the speed of the marble.
The greater the rubber band is stretched, the greater the speed of the marble.
The greater the rubber band is stretched, the lower the speed of the marble.

When a fast-moving glass ball hits the metal cup, what happens to the volume of sound created?
When a fast-moving glass ball hits the metal cup, its large amount of energy creates a low volume of sound.
When a fast-moving glass ball hits the metal cup, its large amount of energy creates a high volume of sound.
When the glass ball rolls slowly down a short ramp, its small amount of energy creates a high volume of sound.
When the glass ball rolls slowly down a tall ramp, its small amount of energy creates a low volume of sound.
