Question

We can find the speed of a moving object if we know the mass and the distance traveled by it.

• A. True
• B. False

Answer 1

The correct option is B False

1. Speed: The speed of an object is defined as the distance (d) covered by it in a unit of time (t).
2. The unit of speed is m/s or km/h.
3. The speed of an object can be calculated as-
   $Speed\left(m{s}^{-1}\right)=\frac{Dis\tan ce\left(m\right)}{Time\left(s\right)}$
4. Since the speed of an object does not depend upon its mass, therefore to calculate the speed we need not find the mass of the object.
5. Hence the given statement is false.
