Question

a body is moving in a square field of side 20 m calculate the distance and displacement in two rounds​

Answer 1

Answer:

The distance in 2 rounds = 160 m(as perimeter of square = 4 X side = 4 X 20 = 80 m[One round] and 2 rounds distance = 80 X 2 = 160 m)

And,

The displacement in 2 rounds is zero because displacement = least distance from initial position to final position i.e. the body completed 2 rounds but came at the same position where he started so the final position coincides the initial position.

Step-by-step explanation:

Answer 2

Answer:

Given:

A body is moving in a square field of side 20 m.

To Find:

Distance =?

} in two rounds

Displacement=?

Solution:

side of a square=20 meter

A body cover a distance in two rounds=

perimeter of a square×2

20×4×2..

→160 m

Therefore, distance=160 m

Now displacement,

A body is starting from a specific point and again stop on that specific point.

So, displacement=0

Definitions→

1) Distance=

Actual length travelled by an object.

2) Displacement=

Minimum distance between the final point and the initial point.
