Give an example of zero work done

WebSo, during the horizontal motion, since the work done is zero, we can just get rid of the displacement, that displacement doesn't come into our formula. So let's get rid of that displacement. And so the only displacement that matters to us is the one that happens in the direction of the force of gravity, right? And that's what we meant earlier. WebNov 20, 2024 · Zero Work Done. Zero work done is either when there is no force applied to the object or when force is applied, but the displacement is zero. For example, if the force is applied hard against the wall, the …

The video version of its … WebSep 28, 2024 · For example, if a person tries to push a wall, he is applying force yet the wall does not move, so the displacement of the wall is zero, and hence work done is zero. How can work be negative if it is a scalar? If the displacement is in the opposite direction of the force, then work is negative. guams biggest earthquake https://shopbamboopanda.com

WebApr 7, 2024 · When the angle between the force applied and the displacement is 90 ∘ , then the work done will be, W = F s cos θ ⇒ W = F s cos 90 ∘ ∴ W = 0 Thus, the value of work done will be zero and this work is called the “zero work”. The examples of this type of work, that is zero work are: The normal force or the gravitational force acting downwards. Web(a) When the displacement of the body is along the direction of the force applied, work done is positive. E.g. Gravitational force does positive work on a body falling from some height. (b) When the displacement of the body is opposite to the direction of the force, work done is negative. E.g. work done by friction on a sliding body is negative.
