Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time. nonuniform (not comparable) Not uniform. If the water surface is parallel to the channel bottom flow is uniform and the water surface is at normal depth. Definition: Non-uniform motion is used to mean the movement in which the object does not cover the same distances in same time intervals, regardless of the length of the time intervals. An example of non-uniform motion is a body rotating at a constant speed. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. If an object covers equal distance in equal intervals of time, we can say that the object is moving with a uniform speed.

The basic difference between uniform and non uniform motion is that: In uniform motion, a body moves with a constant speed such as the Motion of earth around the sun. For the first time, this problem is solved by the improved non-uniform B-spline curve fitting approximation (NBSC) method. Thus the particles move in laminas or layers gliding smoothly over the adjacent layer. Since the speed is changing, there is a tangential acceleration in addition to normal acceleration which is the cause of changing speed. Found inside – Page 9Nonuniform motion : It is a motion in which the velocity varies with time. ... v= + 1.0 m/s, t=2.0s According to the definition of acceleration, ... In equation form, angular acceleration is expressed as follows: (10.1.4) α = Δ ω Δ t, where Δ ω is the change in angular velocity and Δ t is the change in time. Velocity- Time Graph. Uniform Motion: Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time. Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time. nonuniform (not comparable) Not uniform. If the water surface is parallel to the channel bottom flow is uniform and the water surface is at normal depth. Definition: Non-uniform motion is used to mean the movement in which the object does not cover the same distances in same time intervals, regardless of the length of the time intervals. An example of non-uniform motion is a body rotating at a constant speed. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. If an object covers equal distance in equal intervals of time, we can say that the object is moving with a uniform speed.
