Question

(2) Explain why the below statements about displacements are not true.
1. Displacements cannot be zero
2. The magnitude of displacements is always greater than the distance travelled.​

Answer 1

Answer:

if you travel A certain distance and come back to the same original. The displacement can be zero thus the first point is wrong

take the same example if you travel distance and come back to the same original. Then and the distance travelled will always be greater and displacement will be zero and if you do anything then the displacement will be always equal to or smaller than distance travelled

Answer 2

Explanation:

Displacement is a shortest distance between initial and final point.

➡In the first statement, it says that displacement can not be, zero but it is wrong .let us suppose a body travels a distance from if moves A to B and then return back to A then the displacement will be zero, because the shortest distance is Zero

➡2nd statement says that The magnitude of displacements is always greater than the distance travelled ,this statement is wrong because displacement is less than or equal to distance but not more than distance, because it is a shortest distance.
