Question

which form of energy is exemplified by the motion of wheels on a bicycle?
a thermal
b mechanical
c chemical
d electromagnetic

Explanation:

To determine the energy form for the motion of bicycle wheels, we analyze each option:

• Thermal energy is related to heat, not motion, so option a is incorrect.
• Mechanical energy is associated with the motion and position of an object. The wheels' motion is a form of mechanical energy (kinetic energy, a type of mechanical energy), so option b is correct.
• Chemical energy is stored in chemical bonds (e.g., in food or fuel), not related to the wheels' motion, so option c is incorrect.
• Electromagnetic energy involves electromagnetic waves (e.g., light, radio waves), not the motion of bicycle wheels, so option d is incorrect.

Answer:

b. mechanical
