A force of $7\ N$ acts on an object. The displacement is, say $8\ m$, in the direction of the force. Let us take it that the force acts on the object through the displacement. What is the work done in this case ?

Academic Physics NCERT Class 9

As given, displacement of the object $d=8\ m$

Force acted on the object $F=7\ N$

Now, Work done$=Force\times Displacement$

$=7\times8=56\ J$

Thus, the work done is $56\ J$.

Write an expression for the work done when a force is acting on an object in the direction of its displacement.
The work done on an object does not depend on the:(a) displacement(b) angle between force and displacement(c) force applied(d) initial velocity of the object
The work done by a force \( \vec{F} \) during a displacement \( \vec{r} \) is given by \( \vec{F} \cdot \vec{r} \). Suppose a force of \( 12 \mathrm{~N} \) acts on a particle in vertically upward direction and the particle is displaced through $2.0m$ in vertically downward direction. Find the work done by the force during this displacement.
The work done on an object does not depend upon the: (a) displacement (b) force applied (c) angle between force and displacement (d) initial velocity of the object
When a body like earth is moving in a circular path the work done in that case is zero because:Centripetal force acts in the direction of motion of the bodyCentripetal force acts along the radius of circular pathGravitational force acts along the radius of circular pathCentrifugal force acts perpendicular to the radius of circular path
(a) What happens to the work done when the displacement of a body is at right angles to the direction of force acting on it? Explain your answer.(b) A force of $50\ N$ acts on a body and moves it a distance of $4\ m$ on a horizontal surface. Calculate the work done if the direction of force is at an angle of $60^{o}$ to the horizontal surface.
The work done is zero ifa. The body shows displacement in the opposite direction of the force applied. b. The body shows displacement in the same direction as that of the force applied. c. The body shows a displacement in perpendicular direction to the force applied. d. The body masses obliquely to the direction of the force applied.
When we pedaling the bicycle it stops because:I. The earth’s gravitational force acts on it II. It is not accelerated III. No unbalanced force acts on it IV. Frictional force acts on it
The velocity of a body of mass $10\ kg$ increases from $4\ m/s$ to $8\ m/s$ when a force acts on it for $2\ s$.(a) What is the momentum before the force acts?(b) What is the momentum after the force acts? (c) What is the gain in momentum per second?(d) What is the value of the force?
The velocity of a body of mass 10 kg increases from 4 m/s to 8 m/s when a force acts on it for 2s. What is the momentum before the force acts?
e and the displacement caused due to the force is 180°, then the displacement is in the opposite direction of the applied force.
The velocity of a body of mass 10 kg increases from 4 m/s to 8 m/s when a force acts on it for 2 s. What is the momentum after the force acts?
If the work done by a force in moving an object through a distance of 20 cm is 24.2 J, what is the magnitude of the force?
A child on a skateboard is moving at a speed of 2 m/s. After a force acts on the child, her speed is 3 m/s. What can you say about the work done by the external force on the child?positive work was donenegative work was doneZero work was doneInfinite work was done
A force acts for 0.5 seconds on an object having mass 1.2kg initially at rest. The force then stops to act but the object moves through 4m in the next 2 sec. Find the magnitude of the force?
