What is the difference between uniform motion in a straight line and circular motion ?
What is the difference between uniform motion in a straight line and circular motion ?
| Uniform linear motion | Uniform circular motion |
| $(i)$ The body moves along a straight line. | $(i)$ The body moves around a circular path. |
| $(ii)$ Acceleration js zero, as velocity remains constant. | $(ii)$ It is an accelerated motion, due to continuous change in velocity which happens due to change in direction. |
