The formula for work is used to calculate work done in moving an object. Understand the work formula with Derivation, Examples, and FAQs.
The general formula for work and for determining the amount of work that is done on an object is: W = F × D × cos(Θ) where W is the amount of work, F is the vector of force, D is the magnitude of displacement, and Θ is the angle between the vector of force and the vector of displacement.
Work done = force × distance moved in the direction of the force. is done when energy is transferred from one store to another. Work is also done when a force causes an object to move.
For example, if a force of 10 newtons (F = 10 N) acts along a point that travels 2 metres (s = 2 m), then W = Fs = (10 N) (2 m) = 20 J. This is approximately the work done lifting a 1 kg object from ground level to over a person's head against the force of gravity.
4 cze 2024 · W = Fs. Where: W = work done (J) F = average force applied (N) s = displacement (m) In the diagram below, the man’s pushing force on the block is doing work as it is transferring energy to the block. Work is done when a force is used to move an object over a distance.
Examples on Work Done. Example 1. A box is dragged horizontally across a floor by a 100 N force acting parallel to the floor. What is the work done by the force in moving it through a distance of 8 m. F = 100 N.
30 maj 2024 · Step 1: List the known quantities. Distance, s = 23 m. Force, F = 500 N. Step 2: Write out the equation relating work, force and distance. Work = F × s.
