Question

why the gravitational potential formula is ( -- ) of gravitational potential energy by mass

i.e ,. V=-GM/r why negative???​

Answer 1

Answer:

because gravity attracts any thing towards it

...so the velocity is decreased............

Answer 2

Answer:

these is why because Derivation of Gravitational Potential Energy Equation When, h<<R, then, R + h = R and g = GM/R2. ⇒ Note: ... At a point in the gravitational field where the gravitational potential energy is zero, the gravitational field is zero.
