Levi has joined the school’s archery team. His science teacher has asked him to apply the concepts of potential and kinetic energy to the sport of archery. Which of the following most accurately applies the concepts of kinetic and potential energy to the sport of archery?

• When Levi pulls the bow back, this is an example of potential energy. When he releases the bow, the forward motion of the bow releases thermal energy into the arrow.

• When Levi is holding his bow and arrow, this is an example of kinetic energy. When he releases the arrow, the moving arrow is an example of potential energy.

• When Levi releases the arrow, the friction applied by the bow releases potential and kinetic energy that is transferred through the arrow.

• When Levi is holding his bow and arrow, this is an example of potential energy. When he releases the arrow, the moving arrow is an example of kinetic energy.

Which of the following best explains the difference between kinetic and potential energy?

• Potential energy is the energy an object has when it is at rest. Kinetic energy is the stored energy an object has when it is in motion.

• Kinetic energy is the energy an object contains when it is in motion. Potential energy is the stored energy an object has when it is at rest.

• Potential is the stored energy an object has when it is in motion. Kinetic energy is the energy an object has when it is at rest.

• Kinetic energy is the energy an object contains at rest. Potential energy is the energy an object contains when it is in motion.

Which of the following statements best explains the position of the basketball in each of the four positions?
