Revision notes on Work Done for the CIE IGCSE Physics syllabus, written by the Physics experts at Save My Exams.
Force-Distance graphs If the force is non-uniform then the formula W = F × d does not apply. Instead, we present the information as a force-distance graph and calculate the area beneath the graph to find the work done by the force. Recall the other “area under a graph”, which is the force-time graph that gives the impulse of a force.
The amount of work done upon an object depends upon the amount of force (F) causing the work, the displacement (d) experienced by the object during the work, and the angle (theta) between the force and the displacement vectors.
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Learn how to calculate the work done on an object using a force vs. distance graph and see examples that walk through sample problems step-by-step for you to improve your physics...
Work is the measure of energy transfer when a force ' F ' moves an object through a distance ' d '. So when work is done, energy. has been transferred from one energy store to another, and so:...
20 lut 2022 · From the definition of work, we see that those units are force times distance. Thus, in SI units, work and energy are measured in newton-meters . A newton-meter is given the special name joule (J), and \(1 \, J = 1 \, N \cdot m = 1 \, kg \, m^2/s^2\).
