Question

Can the speed of a particle be negative? Can the
velocity of a particle be negative? Give reasons in
support of your answer.
​

Answer 1

No the speed can't be negative because it is a scalar quantity so it doesn't have a direction hence it cannot be negative...

the velocity can be negative because it is a vector with definite direction.(-) velocity indicates backward motion hence it can be negative..

Answer 2

Mate here is your answer....


The speed of any particle will not be negative..because it is a scalar quantity

but the velocity maybe negative because it is a vector quantity

hope it helps you
