Question

is it necessary for body in uniform motion to move along a straight line path. Give an example to justify your reply​

Answer 1

Answer:

And yes, a body needs to travel in a straight line in order to execute a uniform motion. In fact, it must not just travel in a straight line but also must always go in the same direction (I remember that on a straight line there are two directions of motion possible),i.e., “it must never change its direction” is the only condition it has to satisfy to qualify for being in uniform motion (I forgot to mention explicitly that the speed needs to be constant first; so technically two conditions).

Answer 2

Answer:

The displacement of a body in uniform motion is the same for the same interval of time, no matter what the interval. ... For the same interval of time, no matter what the interval, the displacement is zero and hence the same. In this special case the body need not travel in a straight line in order to have uniform motion.
