  • Kinetic Energy – The energy an object possesses due to its motion, calculated as 0.5 × mass × velocity².
  • Power – The rate at which work is done or energy is transferred, calculated as work done divided by time.
  • Acceleration – The rate of change of velocity of an object, which in this case is derived from the change in speed over time.
