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. WebFeb 18, 2024 · Explanation: If displacement and force are perpendicular to each other, work done is zero. ⇒ θ = 90o so W = 0. Work done is zero i.e., force and displacement are perpendicular to each other is verified in the following cases: a) When a body is in circular motion no work is done by centripetal force. b) In pulling a body on a horizontal ...
What are some examples of zero work done? - Quora
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. WebNumerically the positive work done raising it was cancelled by the negative work done lowering it resulting in zero work being done overall on the book. (The situation is different for the smashed walnut, insect, or square peg.) algebra Work is done whenever a force results in a displacement. how to get to northrend from orgrimmar retail
What is zero work? Physics Questions - Toppr Ask
WebLet us consider some cases where work is not done: Work is zero if applied force is zero (W=0 if F=0): If a block is moving on a smooth horizontal surface (frictionless), no work will be done. Note that the … WebMar 30, 2024 · I'll give two examples of when zero net work may occur: 1) A circular orbiting satellite. A circular orbiting satellite, moving in a circle, is always accelerating towards the center of the orbit (let's say Earth). The direction of acceleration, and force (see Newton's equation), happen to be perpendicular to the velocity (i.e. motion, or ...
