Question

Explain Gravitational Potential ​

Answer 1

Gravitational Potential at a point in the gravitational field is defined as rhe amount of work done in bringing a body of unit mass from infinity to that point without acceleration.

I = -dv/dr

Negative sign indicates that the direction of intensity is in the direction where the potential decreases.

Answer 2

lt is the negative of work done by gravitational force in moving a body of unit mass from infinity to its position.

OR

lt may also be defined as the work done by external force in bringing a body from infinity to its position without any acceleration that means with constant velocity

$\huge{ \boxed{ \boxed{V= \frac{ - W_G}{m}}} }$

]} Its SI unit is Joule per kg i.e. J/Kg.

∆}]

For a system of two masses M and m are separated by a distance r, the gravitational potential at the position of m will be:-

$\huge{ \boxed {\boxed{V = \frac{ - GM}{r}}}}$
