Speed | Velocity |
1. The rate of change of distance is called speed. | 1. The rate of change of displacement is called velocity. [1 Mark] |
2. Speed is a scalar quantity | 2. Velocity is a vector quantity. [1 Mark] |
3. Average speed cannot be zero i.e, distance cannot be zero. | 3. Average velocity can be zero i.e, displacement can be zero. [1 Mark] |
