Question

1. Distinguish between distance and displacement .A person moves along the circumference of the circle of radius 1m. Find the distance and displacement for half rotation​

Answer 1

Explanation:

Distance is the total distance travelled. And displacement is the resultant shortest distance between your initial and final position.

Radius = 1m

Hence distance travelled = Circumference of the circle

= 2πr

= 2 × π × 1

= find out yourself :)

Then, displacement = 0

Because in circular path he started from one point and ended in same point. hence 0
