NCERT Gist: Motion Notes - UPSC

- The shortest distance measured from the initial to the final position of an object is known as the displacement.
- Automobiles are fitted with a device that shows the distance travelled. Such a device is known as an odometer.
- As the object covers equal distances in equal intervals of time, it is said to be in uniform motion.
- If the athlete moves with a velocity of constant magnitude along the circular path, the only change in his velocity is due to the change in the direction of motion.
- The motion of the athlete moving along a circular path is, therefore, an example of an accelerated motion.
