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 … Webzero, then its speed must have changed. (b) If the net or total work done on a particle was not zero, then its velocity must have changed. (c) If the net or total work done on a particle was not zero, then its direction of motion could not have changed. (d) No work is done by the forces acting on a particle if it remains at rest.
WebThe following reactions are examples of zero order reactions that are not dependent on the concentration of the reactants. The reaction of hydrogen with chlorine (Photochemical reaction). H 2 ( g) + C l 2 ( g) → h v 2 H C l ( g) Decomposition of nitrous oxide over a hot platinum surface. 2 N 2 O → P t ( h o t) 2 N 2 + O 2. WebAnd the reason they haven't done it is because they couldn't come up with a good answer. There's no good answer here, no good definition. And because of that, any non-zero number, divided by zero, is left just "undefined." 7 divided by …
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. 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.
