SPEEDIt is the distance

travelled in unit timeSpeed=Distance travelled/Time

Average speed=Total distance travelled/Total time

Averages of speed=Sum of speed/Number of speed

The physical quantities have only magnitude and no direction are called scalar quantities

Eg:Speed,Distance

The physical quantities posses both magnitude and direction are called vector quantities

Eg:velocity,accileration

DISPLACEMENT

It is the change of position along a particular direction

VELOCITYIt is the rate of change of displacement

velocity=Displacement/Time

Unit=m/s

ACCELERATIONIt is the rate of change of velocity

Acceleration=Change of velocity/Time

Unit=m/s
