WebFind out the amount of work done by the force in moving the object through a distance of 8 m. Solution: Given: F = 100 N, d = 8 m Since F and d are in the same direction, θ = 0, [θ is the angle of the force to the direction of … WebApr 7, 2024 · The examples of this type of work, that is zero work are: The normal force or the gravitational force acting downwards. This force acts perpendicular to the surface of the earth. While walking a man holding an object. The displacement of a person running forward on a horizontal surface. (The gravitational force will be perpendicular).

Give one example where work done on an object is negative
WebThat's right, you can do work less than zero, in physics. Let's find out how. Now in a previous video, we saw how to calculate work. It's calculated as force acting on an object multiplied by the displacement of that object. This means that to do work, in physics, you need to push or pull on something, and while pushing or pulling, you have to ... WebSolution Verified by Toppr Work done (W) = force ∗ displacement. Hence, work is said to be done when there is displacement. In this case the wall does not displace from its position even though the force is applied and since displacement is zero work done is said to be zero.
