Question

diffrence between speed and vilocity

Answer 1

speed -
1) speed is the rate of change of distance with time
2)it is a scaler quantity.
3)speed of the body is always positive.

velocity-
1)velocity is the rate of change of displacement with time.
2)it is a vector quantity.
3)velocity of the body can be positive as well as negative

Answer 2

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..
