Question

what is the difference between uniform motion in a straight line and circular motion

Answer 1

Uniform motion in straight line is referred as the motion in which body travels in one dimension only with constant velocity or we can say that there is a constant change in the position of the body with respect to time but in one dimension.

Position-time graph:
This represents the relation between the position of the body and time taken by the body.

When body moves with constant velocity, graph between position and time is a straight line.

Answer 2

Uniform linear motion is a motion with a constant velocity,whereas uniform circular motion is the motion with a constant speed.

uniform circular motion where a centripetal acceleration always acts towards the centre and always perpendicular to the velocity of the object.

uniform linear motion is the motion where an object has no acceleration and is travelling with constant velocity.
