Scalar quantities are physical quantities with no direction on magnitude

Vector quantities are quantities with magnitude + direction.

SCALAR Vector

time displacement

distance acceleration

speed Speed

DISTANCE: 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 Acceleration

Speed: Distance moved per unit time

Speed= Distance travelled/ Time taken

the speed of an object at a particular instant is known as instantaneous speed

Velocity: rate of change of displacement

Velocity= displacement/time taken
