Introduction to Uniform Motion
In this lesson let me help you on uniform motion. A motion is said to be uniform if the particle covers equal distances in equal intervals of time, however small these intervals of time may be , always in the same direction. Strictly speaking , no motion is uniform.
When a particle has uniform motion, neither the magnitude nor the direction of velocity changes , so the velocity is constant in uniform motion and is equal to Instantaneous velocity of the particle.
So uniform is a relative concept. If an object A is in uniform motion relative to another object B, then from B's view there appear to be no force applied to A; i.e. it appears to be neither accelerating nor decelerating, nor changing directions or moving in a curve. The same should apply vice versa.This could also help us on examples of physical changes
when a particle possess uniform motion, it's velocity- time graph is a straight line parallel to time axis.If the velocity of the particle is taken as positive, the straight line is taken above the time axis and if it is negative, then the V-t graph will be a straight line below the time axis
