Energy, work and power — practice question

In a bicycle braking system, energy is moved from a kinetic energy store to an internal energy store. A motor changes energy from a chemical energy store (battery) into a kinetic energy store. What makes these energy transfers possible?

  • Abraking system: electrical work; motor: mechanical work
  • Bbraking system: electrical work; motor: electrical work
  • Cbraking system: mechanical work; motor: mechanical work
  • Dbraking system: mechanical work; motor: electrical work
