The diagram shows a rubber band in two different states. Which of the following statements describes the diagram most accurately?

• The rubber band on the left has more kinetic energy than the one on the right.

• The rubber band on the right has more kinetic energy than the one on the left.

• The rubber band on the right has more elastic potential energy than the one on the left.

• The rubber band on the left has more elastic potential energy than the one on the right.

Suppose chemists in a lab are trying to release as much energy as possible from a chemical reaction. Which of the following options best represents a valid idea that will allow them to achieve their goal?

• The chemists increase the temperature, which leads to more molecules forming bonds.

• The chemists increase the amount of space where the reaction occurs, which leads to more molecules colliding and forming bonds.

• The chemists increase the stability of the bonds in molecules, which makes it harder to release energy.

• The chemists decrease the stability of bonds in molecules, which makes it easier for energy to be released.

• A. A; B

• B. B; A

• C. A; A

• D. B; B

Based on the diagrams of a marble ramp and a spring in different states, which statement best explains the difference between kinetic energy and elastic potential energy?

• Kinetic energy is the energy of motion, as seen with the moving marble, while elastic potential energy is stored in objects like compressed or stretched springs.

• Kinetic energy is stored in objects at rest, while elastic potential energy is only found in liquids.

• Elastic potential energy is the energy of motion, while kinetic energy is stored in stretched objects.

• Kinetic energy and elastic potential energy are the same and cannot be distinguished.

Kinetic and elastic potential energy can be compared and contrasted using the diagrams discovered by the students. Which statement best summarizes their differences?

• Kinetic energy is energy of motion, while elastic potential energy is stored in stretched or compressed objects.

• Kinetic energy is stored in objects at rest, while elastic potential energy is energy of motion.

• Both kinetic and elastic potential energy are only present in moving objects.

• Elastic potential energy is only found in liquids, while kinetic energy is only found in solids.

Describe how chemical energy is depicted in the diagram. How is that chemical energy changed into kinetic energy?

• Chemical energy is shown as stored energy in molecules and is changed into kinetic energy through a process such as combustion or cellular respiration.

• Chemical energy is shown as light energy and is changed into kinetic energy by absorbing sunlight.

• Chemical energy is depicted as electrical energy and is changed into kinetic energy by using a battery.

• Chemical energy is shown as sound energy and is changed into kinetic energy by producing vibrations.

3. Suppose a group of students conduct a research project to determine the differences between kinetic energy and elastic potential energy. They found two diagrams while researching the topic. The first diagram shows a marble ramp and the marble’s position before it is released. The second diagram shows a spring.

5. Compare and contrast kinetic and elastic potential energy using the diagrams discovered by the students.
