Question

difference between speed and velocity

Answer 1

the short answer is that velocity is the speed with a direction, while speed does not have a direction.Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc....Velocity is a vector quantity -- when giving the velocity we must specify the magnitude (the speed) and the direction of travel. For example you might drive 100km/hr (the speed) in a northerly direction.This is analogous to the difference between distance (a scalar quantity) and displacement (the distance with direction.)

Answer 2

SPEED-

》Speed is distance travelled per unit time or the rate of change of distance.

》It is a scalar quantity.

》Speed can never be zero. It can also never be negative.

》Speed has no direction.

》It never decreases with time in any case.

》It is never zero for a moving body.

VELOCITY-

》Velocity is displacement per unit tike or rate of change of displacement.

》It is a vector quantity.

》It can be zero, positive or negative depending upon the cases.

》It has direction.

》It decreases with time.

》It can be zero for a moving body
