Question

The units of speed and velocity are different.

• A. True
• B. False

Answer 1

The correct option is B False

Speed:

1. Speed is the rate of change in the distance of an object.
2. $\mathrm{Speed}=\frac{\mathrm{Total}\mathrm{distance}\mathrm{traveled}\left(\mathrm{meter}s\right)}{\mathrm{Total}\mathrm{time}\mathrm{taken}\left(\mathrm{seconds}\right)}$
3. The SI unit of velocity is meters per second (m/s).

Velocity:

1. Velocity is the rate of change of displacement of an object.
2. $\mathrm{Velocity}=\frac{\mathrm{Total}\mathrm{displacement}\left(\mathrm{meter}s\right)}{\mathrm{Total}\mathrm{time}\mathrm{taken}\left(\mathrm{seconds}\right)}$
3. The SI unit of velocity is meters per second (m/s).

Therefore, velocity and speed both have the same SI units.

Hence, the given statement is false.
