State whether the following statement is true or false:
$A$ quantity which can be completely specified by magnitude as well as direction is called a scalar quantity.

$A$ body thrown in the vertically upward direction rises up to a height $h$ and comes back to the position of its start. Calculate: $(a)$ the total distance travelled by the body and $(b)$ the displacement of the body. Under what condition will the magnitude of the displacement be equal to the distance travelled by an object?

Ravi told his friend that his house is $1 \,km$ toward south from the main Post Office. Express the displacement and the distance moved by the friend from the Post Office when he arrives at Ravi's house. Mention the reference point chosen by you.

In which of the following cases of motion,are the distance moved and the magnitude of displacement equal?

State whether the following statement is true or false:
$A$ body is said to be at rest if it does not change its position with respect to its reference point.

Under what condition will the magnitude of the displacement be equal to the distance travelled by an object?
