(a) Displacement= change in position which includes both magnitude and direction
(b) Velocity = displacement/time
V=dx/dt
(c) Acceleration= change in velocity = velocity/time;
a= dv/dt = d/dt(dx/dt)
Direction is Not Important in Scalar quantities:
(a) Distance
(b) Speed= total distance/time which only describe how 'fast' is a particle moving without telling which direction
