Question

1.What is the displacement of the body if it returns to the same point from where it started? Give one example from daily life.

2. When do the distance and magnitude of displacement become equal?​

Answer 1

Answer:

1.Displacement will be zero. For eg. if you are running on a circular track.

2. Distance and displacement becomes equal when an object move on a straight path.

Answer 2

Explanation:

1). If a body after travelling, comes back to its starting point, the displacement travelled by the body is zero.

eg => When a body moving in a circular path reaches it's original position after one round, then the displacement at the end of one round is zero, but the distance travelled by the body is equal to the circumference of the circular path (2πr if r is the radius of the circular path)

2). When the motion is along a fixed direction, the magnitude of displacement is equal to that of distance.
