Learn the difference between uniform and non- uniform motion , and how to graph them. See examples of uniform motion with constant velocity and acceleration, and non- uniform motion with variable acceleration and deceleration. Motion of a Body " Motion of a Body" is defined as the change in the position of the body with respect to the time taken. Some examples of objects exhibiting motion are a moving bus, the hands of a clock, the needle of a sewing machine, a cyclist cycling in a park, etc. Any object can majorly perform two types of motion which are uniform motion and non- uniform motion . What is Motion ? In physics, motion is defined as the change in position of a body relative to its surroundings over time. The ... Learn the definitions, examples and comparison of uniform and non- uniform motion in physics. Uniform motion is when an object travels in a straight line with constant speed, while non- uniform motion is when an object travels with varied speed or acceleration. In this article, you will learn about uniform linear motion , i.e., motion with constant velocity along a straight line.
