Question

draw relacity -time graph, when an object has. a )uniformly acceleration motion. b )uniformly retarded motion.

Answer 1

Hey there!


a) During uniform motion the acceleration of the body is 0 therefore the velocity time graph for a uniform motion is a graph line parallel to the time axis where slope (i.e acceleration) = 0
b) During uniformly accelerated motion the graph is a straight line passing through the origin with a constant slope. 
c) During uniformly retarded motion the graph is a straight line downwards which shows decreasing velocity at a uniform rate.
