Derivation of w=mgh Asked by sanjeevrao2704 4th Jun, , 0843 AM Expert Answer If a body of mass m moves down from a height h, the force of gravity or weight acts on the body through a displacement h Thus, workUse the connection between force and potential energy to determine the general form of gravitational potential energy U = mgh applies only for a uniform field, so it does not apply here where the field goes as 1/r 2 F = dU/dr ΔU = ∫ F dr This gives U = GmM/r, if we define the potential energy to be zero at r = infinityAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How works Test new features Press Copyright Contact us Creators

W=mgh derivation
W=mgh derivation-The formula mgh is valid for uniform gravitational field (constant g) which is an approximation of the real gravitational field of the Earth exactly for the case ePotential energy is the work done to take a body to a certain height For a body with mass m, h is the distance to which it is raised and g is the gravitational force acting on the body, then work done W is given as W = force * displacement W = mg * h ∴ W = mgh As the work done is equal to mgh which is gained by the object, potential

Answer To be specific,the work that you're talking about is the 'magnitude' of the work done by gravity on a body in raising it or dropping it through a height 'h' Now in general, the work done by any force 'f' in displacing a body through a certain displacement 'x' is given my Work=scalar proW = mgh Where, W = work done g = acceleration due to gravity h = height of free fall If the angle between gravitational force and direction of motion is 𝚹, then work done due to gravity is given by W = mgh cos 𝚹 So if an object is moving in horizontal direction on the surface of earth, then work done by gravity is 'zero' LLP is an abbreviation for many terms The terms vary from relating to science and medicine, to government and military To discern the term
W = force * displacement W = mg * h ∴ W = mgh As the work done is equal to mgh which is gained by the object, potential energy Ep is given as Ep = mgh Therefore, the above is the derivation of potential energy Stay tuned with BYJU'S for more such interesting articlesW = (Force)(Distance) = F D The footpound combines a unit of force a pound with a unit of distance a foot and is thereby a unit of work or energy 1 footpound is the amount of work that must be done to raise a 1 pound weight by 1 foot This also gives the change in potential energy of the 1 pound weightWhat does MGH abbreviation stand for?
It is also more convenient to divide the work into two terms 1) the flow workdone by the system which is p 2 v 2p 1 v 1, and 2) any additional work which we will term external work or shaft work, w s Then we have or We will call this the steady flow energy equation For an ideal gasdh=c p dT soThis video shows how to derive the equation W = mg This video is giving an examples of deductive reasoningDiscord is the easiest way to communicate over voice, video, and text Chat, hang out, and stay close with your friends and communities
