Question

heavy box is kept on a smooth inclined plane and is pushed by a force f acting parallel to the plane does the work done by the force f as the box goes from A to B depend on half hours the box was moving at A and B done the work by the force of gravity depend on this ​

Answer 1

Answer:

the force of gravity depends on

Forces acting on the box are force F, Normal force N and weight of the box mg. Work done by the individual force F does not depend on how fast the box was moving at A and B (velocities) neither the work done by the individual force of gravity (mg). Only the work done by the resultant force on the box depends on the velocities at A and B

Answer 2

The workdone by the force of gravity depends upon the velocities used and time taken.

Explanation:

Given Data

Force acting on the box = F

Normal force acting on the box =N

Weight of the box (w) = Product of mass (m) and Gravity (g)

(where 'g' is the gravity of earth)

To find - the work done by the force depends on ?

• Workdone is defined as the Product of force and displacement.
• Here a box is moved with a force from the place A to B with initial and final velocities.
• The work done by an object will depends on the amount of force acting and the distance traveled by an object.
• The displacement (distance) can be found by time and velocity.
• Here the Workdone by the force of gravity depends upon the velocities used time taken to done the work from A to B.
