Item EG005004: Increasing the speed of an object increases its motion energy.
How does increasing the speed of an object affect the kinetic energy (motion energy) of the object?
- Increasing the speed of an object decreases its kinetic energy.
- Increasing the speed of an object increases its kinetic energy.
- Increasing the speed of an object does not affect its kinetic energy.
- Whether or not the kinetic energy of an object is affected depends on how much its speed was increased.
