How Do You Calculate Useful Work Done? Work is done whenever a force moves something over a distance. You can calculate the energy transferred, or work done, by multiplying the force by the distance moved in the direction of the force. How do you calculate useful work efficiency? The work efficiency formula is efficiency =
Is Work Dependent On Angle Between Force And Displacement? The acting force on the body : Work is directly proportional to the acting force at constant displacement and constant angle between force and displacement . The displacement of the body : Work is directly proportional to the displacement at constant force and constant angle between
What Is The Angle Between Force And Displacement For Work Done To Be Positive And Negative? If the force is parallel to the direction of the displacement of the body i.e., θ=0∘ the work done will be positive. If the force is anti-parallel to the direction of displacement of the body i.e., θ=180∘ the work
