How does increasing the speed of an object affect the motion energy (kinetic energy) of the object?

  1. Increasing the speed of an object decreases its motion energy.
  2. Increasing the speed of an object increases its motion energy.
  3. Increasing the speed of an object does not affect its motion energy.
  4. Whether or not its motion energy is affected depends on how much its speed was increased.
