Item RG120002: Energy is transferred between to magnets when there is a change in speed.
A girl moves Magnet A close to Magnet B as shown above. When Magnet A is a certain distance from Magnet B, Magnet B begins to move toward Magnet A. The speed of Magnet B increases as it moves toward Magnet A. Is energy transferred while Magnet B moves toward Magnet A?
- No, energy is not transferred because magnets do not transfer energy unless they touch.
- No, energy is not transferred because magnets do not have any energy.
- Yes, energy is transferred because there is a change in speed.
- Yes, energy is transferred, but the transfer of energy is not related to the change in speed.
