Energy: Forms, Transformation, Transfer, and Conservation
Motion energy (kinetic energy) is associated with the speed and the mass of an object.
Item EG005003: Increasing the speed of an object increases its motion energy.
How does increasing the speed of an object affect the motion energy (kinetic energy) of the object?
- Increasing the speed of an object decreases its motion energy.
- Increasing the speed of an object increases its motion energy.
- Increasing the speed of an object does not affect its motion energy.
- Whether or not its motion energy is affected depends on how much its speed was increased.
