Question

difference between speed and velocity

Answer 1

velocityis 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....

Answer 2

Speed and velocity are not same..
1 Speed is the ratio of total distance and time
And velocity is the ratio of sight and time
2 velocity can be zero (0) but speed cannot be zero....
