Question

A body moves in a circular path of diameter D and covers half circle from its initial point. i)What is the distance travelled? ii) What is the displacement?

Answer 1

Answer:

The diameter of the given circle is b.

So the circumference of the circle will be pi*b.

if a body moves in a circular path and cover half circle then, its distance covered will be half of the circumference. So that is pi*b/2.

Now, displacement, it is obviously not equal to the distance. It is equal to the diameter that is the value b.

So conclusion, Distance Traversed = pi*b/2

and displacement = b.

Distance > Displacement.

Explanation:

Answer 2

The diameter of the given circle is b.

So the circumference of the circle will be pi*b.

if a body moves in a circular path and cover half circle then, its distance covered will be half of the circumference. So that is pi*b/2.

Now, displacement, it is obviously not equal to the distance. It is equal to the diameter that is the value b.

So conclusion, Distance Traversed = pi*b/2

and displacement = b.

Distance > Displacement.
