(b) The physical quantity which gives both, the ___ and _____ of motion of a body is called its velocity.


(c) A motorcycle has a steady acceleration Of 3 m/s2. This means that every second its ………increases by ………… .


(d) ___________ is the rate of change of displacement. It is measured in m/s.


(e) ____________ is the rate of change of velocity . It is measured in ………………… .

a. Displacement, Distance

>Displacement depends on direction but distance does not.


b. speed, direction


>velocity = displacement/ time and is directional


c. speed, 3m/s


> acceleration = speed/time


d. Velocity


> Velocity is directional hence it is displacement/ time


e. Acceleration, m/s2


>a = v/t
