Question

22. In which of the following cases of motion, the distance moved and the magnitude of the displacement are equal?

OPTIONS
a) If the car is moving on a straight road
b) If the car is moving in circular path
c) The pendulum is moving to and fro
d) The earth is moving around the sun​

Answer 1

Explanation:

The distance moved and magnitude of displacement are equal only in the case of motion along a straight line. Because displacement is the shortest path between initial and find path. So, for car moving on straight road, distance moved and magnitude of displacement are equal.If the car is moving on a straight road

Explanation: In all other cases, displacement can be less than distance.

Displacement is the shortest distance traveled by an object while the distance is the total distance traversed by the object. In the case of linear motion, the displacement of the object is equal to the distance covered
