Power |
|
|
| The new frame is then attached to a chassis with the wheels and an engine. The engine will turn the wheels and make the coach move. |
| Fuel |  |
Buses and coaches use diesel fuel for their engines to produce energy to make them move. |
|
We eat all kinds of food to give us energy to move, grow and stay healthy. |
Without food our bodies would quickly run out of energy and stop working, in the same way a bus or coach would stop if it had no fuel for the engine. |
