Question

draw position time graph for the motion of a body having (i) uniform positive acceleration, (ii) uniform negative accelaration and (iii) zero accelaration​

Answer 1

1) acceleration is uniform

2) acceleration is negative

3) acceleration is zero as velocity is constant

HOPE IT HELPS

Answer 2

Answer:

(i) uniform positive acceleration(Pg1), (ii) uniform negative accelaration (Pg2) and (iii) zero accelaration​(Pg3)

Explanation:

The rate at which velocity changes is called acceleration. The rate of change of velocity in both magnitude and direction at any given point on a trajectory determines the magnitude of the acceleration there.
