Question

what is zero uniform vilocity motion
​

Answer 1

A body moving with a constant velocity in an accelerated motion. When a body is moving with a constant velocity, then its acceleration will be zero, because then the change in velocity (v - u) is zero. ... non-uniformIn displacement time graph, if the graph is a curved line then the velocity of the body is non-uniform.

Answer 2

The linear motion can be of two types: uniform linear motion with constant velocity or zero acceleration; non uniform linear motion with variable velocity or non-zero acceleration. The motion of a particle (a point-like object) along a line can be described by its position , which varies with (time).
