Formula to find work done
Webarea shows displacement/distance, depending on whether it is a speed or a velocity time graph. Work done is directly proportional to distance, hence as rectangles have a larger area, given that the time (length) and magnitude of speed/velocity (height) is the same, more work is done in the rectangular graph.

WebWe have a cell. Let's say this is our cell. And it's given that across the ends of the cell, across the terminals of the cell the potential difference is three volts. And to calculate work done from this number we need to first understand what this number really means. So we have seen in a previous video that volt really means joules per coulomb. WebTo calculate the work done by a spring force, we can choose the x-axis along the length of the spring, in the direction of increasing length, as in Figure 7.7, with the origin at the …
WebW = work done (J, Nm) F = force (N) s = distance moved by force (s) For an angular motion the work done can be expressed as W = F θ r = T θ (2) where W = work (Joules) θ = angle (radians) r = radius (m) T = torque or … WebSteps for Calculating Work Done by an Expanding Gas Step 1: Identify the pressure of the gas.

WebTo calculate the work done. on an object when a force moves it, use the equation: work done = force × distance \[W = F~s\] This is when: work done (W) is measured in joules (J) WebEnergy is a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms. Although we often hear people talking about energy consumption, …
Webwork done = force × distance This is when: work done is measured in joules (J) force is measured in newtons (N) distance moved along the line of action of the force is measured in metres...
WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy. plough and harrow skelmersdaleplough and harrow worcesterWebMay 26, 2024 · θ = 30°.
