A gravitational field is formed by?
A
g=GM/r^2
A massive spherical body of mass M
2
Q
What is gravitational potential energy?
A
Gravitational pontential energy of two bodies is the work that is done in bringing two bodies to their present position from when they were infinitely far apart.
3
Q
What is Gravitational potential (Vg)
A
Gravitational potential at a point p in a gravitational field is the workdone per unit mass in bringing a small point mass M from infinity to point p.
Vg = V/m
Vg = -Gm/very 2
