Question

Q.9 A quantity is measured to be -20m/s.Is it speed or velocity? Give reason.​

Answer 1

Answer:

-20 m/s should be measured as a velocity

Because velocity is a vector quantity.

The vector quantity can be zero or positive or negative.

But the speed is a scalar quantity where it can never be negative.

So, -20 m/s is velocity. ✔️
