Question

The fast-moving vehicles are given a streamlined shape. Why?

Answer 1

Streamlined shape:

1. A streamlined shape pointed at the ends and broad at the middle.
2. It allows very little resistance to the flow of water and air around it.
3. In fast-moving vehicles, their streamlined shape cuts through the air very easily and thus increased their speed.
4. This shape helps to reduce the loss of energy which require to overcome the resistance.
5. It also reduces fluid friction.
