Answer

Brief Explanations:

  • Kinetic energy can transform into heat, sound etc. during a roller - coaster ride.
  • On a roller - coaster, gravitational potential energy is a major source converted to kinetic energy as the coaster descends, but other forms like elastic potential energy (if springs are involved) can also convert to kinetic.
  • Kinetic energy ($K = \frac{1}{2}mv^{2}$) depends on speed. A change in speed means a change in kinetic energy.

Answer:

  • Kinetic energy can be converted into several other types of energy.
  • Only gravitational potential energy can be converted into kinetic energy.
  • A change in an object's speed is evidence that the object's kinetic energy is changing.
