Solution

The correct option is A
non-uniform

Q. If a body is moving in circular motion with constant speed but changing direction then how it can be in non uniform motion as speed is constant?
If it is in nonuniform motion because its direction is changing so we can we can make acceleration non uniform by either changing speed or direction.

Q. In uniform motion, a body travels in a straight line without changing its direction.

Q. Statement 1: An object moving along a straight line with a constant speed is said to be in non-uniform motion.
