Question

Define speed of a given object and give its SI unit.

Answer 1

1. The distance covered by an object at a given interval of time is called the speed of that object.
2. Speed is a scalar quantity.
3. The SI unit of speed is m/s.
4. Speed can be calculated by dividing distance by time.
5. $speed=\frac{dis\tan ce}{time}=\frac{m}{s}$
6. Hence, the Distance covered by an object at a given interval of time is called the speed of that object.
