Question
A body starts from a point $A$ and moves to $B$. If it returns to the same point, find the :
- Displacement.
- Distance.
- Velocity.
- Average speed.
✓
Answer
- Displacement is zero, since it returns to $A$.
- Distance is twice the separation between $A$ and $B$.
- Velocity is zero.
- Average speed $=\frac{\text{total distance}}{\text{time}}$
$=\text{v}\text{ ms}^{-1}$
