Question

Which of the following is NOT characteristic of displacement ? a) It is always positive b) It has both magnitude and direction c) It can be zero d) Its magnitude is less than or equal to the actual length of the the object.

Answer 1

Answer:

D is not the characteristic of displacement.

Answer 2

Answer:

Option (a) that is displacement is always positive is not a characteristic of displacement.

Explanation:

Displacement can be negative, positive and zero too. In short it can be negative too, therefore, it is not always positive.

✡️ Yes, it is true that it's magnitude is less than or equal to the actual length of the the object.

• Displacement ≤ Distance!

✡️ Also displacement is a vector quantity as it have both magnitude and direction i.e., ${\sf{|\vec{s}|}}$
