Question

how to draw velocity time graph for uniform retardation and distance time graph for non uniform motion.

Answer 1

velocity time graph for uniform retardation in straight line downwards
distance time graph for non uniform motion is any zigzag line

Answer 2

Explanation:

(I). Velocity time graph:

Velocity is the vector quantity. its unit is m/s.

Velocity time slope gives acceleration

Retardation is the negative acceleration.

(II).Distance time graph:

Distance is the path length between the two objects.

Distance time slope gives speed.
