Define uniform circular motion. A particle is travelling in a circle of diameter $15 m$ . Calculate the distance covered and the displacement when it completes two rounds.

Open in App

Solution

If a particle is moving with constant speed on a circular path then it is said to have uniform circular motion.

Distance covered in two rounds is,

$s = 2 \times 2 π r$

$= 4 \times 3.14 \times 7.5$

$= 94.2 m$

Total displacement after two rounds will be zero because particle comes at the same initial point.
