Question

An object is moving in a circle of radus r.Calculate the distance and displacement when it completes one full circle

Answer 1

Answer:

distance is 2*pi*r. displacement is 0.

Explanation:

distance is so because the object has moved about the circumference of the circle, therefore distance is the value of circumference. since the object returns to the starting point, the displacement is 0.

Answer 2

Answer:

Distance =2πr and displacement =0

Explanation:

when the object completes one full round ,it starts from A and comes back to A .

Distance = circumference of circle =2πr

Displacement = zero ,as initial position coincides with its final position
