Draw the diagrams a)
to show the uniform motion of a body moving in a straight line.
b)
to show the velocity-time graph for a body moving with
i) uniform velocity
ii) uniform acceleration

Kindlt see Explanation.

Explanation:

A)A body is said to be in a state of uniform motion if ; it travels in a straight line such that the Velocity of motion remains unchanged during a certain time period. In such state of motion, equal distance is covered in equal interval of time during the duration of the motion.

B) Uniform Velocity is attained when the distance moved per unit time over a certain time interval is constant.

Uniform acceleration occurs when Velocity change per unit time is constant over a certain period of time.

Kindly see attached picture for both graphs.
