Obtain an expression for the workdone by a variable force acting On a particle directed along X axis |
|
Answer» The work done by a constant FORCE of magnitude F on a point that moves a displacement d in the direction of the force is the product: W = Fd.Integration approach can be used both to calculate work done by a VARIABLE force and work done by a constant force.The SI unit of work is the joule; non- SI units of work include the erg, the foot-pound, the foot-poundal, the kilowatt hour, the litre-atmosphere, and the horsepower-hour.Key Termswork: A measure of energy expended in moving an object; most commonly, force times displacement. No work is done if the object does not move.force: A physical quantity that denotes ability to push, pull, twist or accelerate a body, which is measured in a unit dimensioned in mass × distance/time² (ML/T²): SI: newton (N); CGS: dyne (dyn)Explanation:hope its HELP U |
