How to calculate work done against friction
Web8 apr. 2024 · So, the work done by the frictional force in the given displacement of the body is $ - 50\mu kJ$. Note: - The coefficient of friction is an important value, as it is different for different materials and surfaces. We have obtained a general value, assuming the value of limiting coefficient of friction to be $\mu $. WebWork done by friction force =∫ F.ds =−(μkN)×10−1 =−0.5×5×10×10−1 =−2.5J Using work energy theorem Work done by force + Work done by friction =ΔK.E Work done by …

WebWork against friction = force of friction x distance = m m block g d block. Setting the work done by friction against the motion equal to the work done on the block by the falling mass allows you to get another evaluation of the coefficient of friction m since you now know all the other parameters in the above equation. Web21 dec. 2024 · How do I calculate work done by force? To calculate work done by a force, follow the given instructions: Find out the force, F, acting on an object. Determine the displacement, d, caused when the force acts on the object. Multiply the applied force, F, by the displacement, d, to get the work done.
