Answer: B. Potential energy is stored energy (e.g., a raised weight); it converts to kinetic energy when released.
Question 2 of 5
The energy an object has due to its motion is called:
Answer: B. Kinetic energy is the energy of motion; potential energy is stored energy based on position.
Question 3 of 5
The greatest amount of available energy in a food chain is at the level of the:
Answer: B. Producers hold the most energy; energy decreases at each higher level.
Question 4 of 5
