Question

a body thrown vertically upwards reaches a maximum height h it then returns to ground calculate the distance travelled and the displacement​

Answer 1

Answer:

Displacement is the actual length gap between starting & finishing points.

In this case, they are same, so

Net displacement is zero.

Distance travelled is the length which is actually covered by the moving body.

As the body goes up for "h" length and comes down "h" length, so

Net distance travelled= h+ h= 2h

Answer 2

Answer: 2h

Explanation: starting point and the reaching points are same.

Thus, as both the points are same there will be no displacement.

Distance is the area covered by the moving obejct so even if the displacement is 0 there can be a certain amount of distance covered.

So

displacement=0

distance= h+h= 2h
