i need gravitational potential not Gravitational potential energy

i know that it is the amount of work done for an object to move from infinity to a certain distance within a gravitational field

all i wanted to know was why is gravitational potential always negative and not positive

Hashir Group TitleBest ResponseYou've already chosen the best response.1
i guess its because the work is not done ..... actually the energy is extracted

Hashir Group TitleBest ResponseYou've already chosen the best response.1
at infinite distance ... gravitational potential =0 and then when we move away from infinity the gravitational potential becomes negative

From the work done against the gravity force in bringing a mass in from infinity where the potential energy is assigned the value zero, the expression for gravitational potential energy is negative

salini Group TitleBest ResponseYou've already chosen the best response.0
it is the work done by an exterrnal force(lets say me) to bring a body from infinity(0 potential) to that point of interest since always we are doing work in the direction of gravitational force it can also be written in its terms but the the ve work part comes here as we are bringing it from infinity the math of getting ve sign:while integrating GM/r^2 the r^2 brings ve sign the physics behind ve sign:the force is one of attraction(binding the bodies) to appreciate this concept consider moving a body from A TO B (higher potential to lower potential) then u will get potential energy difference=UfUi=vedw:1344612622588:dw that circle is earth

The difference between 'Gravitational Potential' and 'Gravitational potential Energy' is that there is no reference to the testmass in the former. So, if you derive it using work done by the gravitational force, you will end up first with the GpE: GpE = \(G\Large \frac{mM}{r}\) Then GP = GpE/m =\(\Large\frac {GM}{r}\)
