Which type of energy transformation occurs in a bicycle when pedaling up a hill?

• A. Kinetic to potential energy
• B. Chemical to kinetic energy
• C. Electrical to mechanical energy
• D. Potential to kinetic energy

Answer: (A)

When pedaling a bicycle up a hill, the primary energy transformation that occurs is from kinetic energy to potential energy. As you pedal, you use your legs to apply force to the pedals, which propels the bicycle forward, converting the chemical energy from the food you've consumed into kinetic energy. This kinetic energy increases as the bicycle moves. However, as the bicycle goes uphill, this kinetic energy is partly transformed into potential energy, which is the energy stored due to its elevated position relative to a lower point. The higher the bicycle climbs, the more potential energy is created, reflecting the work done against gravity. In this context, the kinetic energy resulting from the bicycle's motion is being converted into potential energy as you gain elevation, making it the correct answer regarding how energy is transformed while riding uphill.
