The object must move in a direction not perpendicular to the force.

(B) For work to be done on an object when a force is applied,the object must undergo a displacement in a direction that is not perpendicular to the direction of the applied force. Mathematically,work is defined as $W = \vec{F} \cdot \vec{d} = Fd cos \theta$. For $W \neq 0$,the displacement $\vec{d}$ must have a component along the force $\vec{F}$,meaning $\theta \neq 90^{\circ}$.

$A$ gardener pushes a lawn roller through a distance of $20 \,m$. If he applies a force of $30 \,kg-wt$ in a direction inclined at $60^{\circ}$ to the ground, the work done by the gardener in pushing the roller is (Given: $g=9.8 \,m/s^2$) (in $\,J$)

Under what condition is a force considered constant when it causes displacement?

Easy

View Solution

$A$ particle moves from position $3\hat i + 2\hat j - 6\hat k$ to $14\hat i + 13\hat j + 9\hat k$ due to a uniform force of $(4\hat i + \hat j + 3\hat k) \, N$. If the displacement is in meters,the work done will be ......... $J$.
