Question

score: 129/600
which combination is not correctly matched?
○ pizza; potential energy
○ wind turning a windmill; kinetic energy
○ gasoline; kinetic energy
○ the bond between two carbon atoms in glucose; potential energy
○ leg muscles doing jumping jacks; kinetic energy

Explanation:

Potential energy is stored energy (e.g., chemical energy in food/fuel, bond energy), while kinetic energy is energy of motion. Pizza has chemical potential energy (correct). Wind turning a windmill uses wind’s kinetic energy (correct). Gasoline stores chemical potential energy, not kinetic (incorrect). Carbon bonds in glucose have potential energy (correct). Leg muscles moving in jumping jacks use kinetic energy (correct). Thus, the mismatched pair is gasoline and kinetic energy.

Answer:

gasoline; kinetic energy
