An electric model train climbs up a steep hill track. The train obtains energy from an onboard rechargeable battery.
Complete the sequence of useful energy transfers as the train climbs up the track:
................................→electrical energy→................................ \text{................................} \rightarrow \text{electrical energy} \rightarrow \text{................................} ................................→electrical energy→................................The train can be controlled to speed up, slow down, or stop. Describe the motion and position of the train when it has a large quantity of gravitational potential energy and zero kinetic energy.
As the train climbs, some energy is wasted. State a form of wasted energy and describe what happens to this energy.
