A body thrown in the vertically upward direction rises upto a height $'h^{\prime}$ 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 ?
A body thrown in the vertically upward direction rises upto a height $'h^{\prime}$ 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 ?
$(a)$ Since it travels a distance $h$ upwards and $h$ downwards, therefore, total distance travelled is $h+h=2 h$
$(b)$ As the body returns to its point of throw, therefore, displacement is zero.
Magnitude of displacement can be equal to the distance travelled, if the object is moving along a straight line.
