Question

A body travels from point A to point D along a square path of side 10 m as shown in the above figure. The magnitude of displacement of the body isImmersive Reader (1 Point) 10 m 30 m 40 m 0

Answer 1

Answer:

Explanation:

Distance travelled from A to B = 10 m

Displacement from A to B = 10 m

Therefore distance and displacement are equal if the object travels in the same straight path

(b) Distance travelled from A to C = AB + BC

= 10 + 10

= 20 m

Displacement from A to C = AC = \displaystyle 10\sqrt{2} m.

Therefore distance travelled is always more than the displacement if there is a change in direction of motion

(c) Distance travelled from A, back to A = AB + BC + CD + DA

= 10 + 10 + 10 + 10 = 40 m

Displacement from A, back to A = 0 m

This is because the shortest distance between initial position (A) and final position (A) is zero.

Therefore the displacement of a moving object may be zero but distance travelled cann
