Scalar quantities are physical quantities with no direction on magnitudeVector quantities are quantities with magnitude + direction.SCALAR Vectortime displacementdistance acceleration speed SpeedDISTANCE: The total length covered by a moving object regardless of the direction of motion SI Unit: meter (m)DISPLACEMENT: distance measured in a straight line. meter (m)

Speed ,Velocity and AccelerationSpeed: Distance moved per unit time Speed= Distance travelled/ Time takenthe speed of an object at a particular instant is known as instantaneous speed Velocity: rate of change of displacementVelocity= displacement/time taken
