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.
If a body is involved in rectilinear motion and the motion is consistent, then the acceleration of the body must be zero.
Example of Uniform Motion:
If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant every second.
