"Uniform motion" means speed isn't changing and direction of motion isn't changing.

That's a pretty good descriptive definition of "zero acceleration".

When a body move in uniform motion why and how its acceleration is constant or equal to zero?

'Acceleration' means any change in speed or direction of motion.'Uniform' motion means no change in speed or direction.


When an body is said to be in uniform motion?

When a body is said to be in uniform motion, it means that it is moving in a straight line at a constant speed without changing its direction. There is no acceleration involved in uniform motion, making its velocity remain constant throughout.


What is the example where acceleration is in the direction of non-uniform motion?

Freely falling body is a good example

Define non uniform motion?

Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.


What will be acceleration of a car moving in a circular motion with constant speed.?

If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.


What is force acting on a body with uniform motion?

A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.


When will you say a body is in uniform acceleration non uniform acceleration?

Uniform (or constant) acceleration means that the acceleration doesn't change over time.


Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?

This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.


If a body is acted by a constant force the body will have uniform?

"acceleration"


Can a body moving with constant speed has acceleration?

Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.


What is the definition of non uniform motion in physics?

During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
