However, weight is the force of gravity acting from the middle of the object straight down. And finally, the equation to find out an object's weight is mass multiplied by gravitational field ...

Gravitational potential energy is the energy ... The weight \(W\) of the suit case is a downward force of size \(mg\). In lifting the suitcase, you would have to pull upwards on it with a force ...

All black holes have the same force constant F inflating ... see figure 2. This equation is a contradiction, because the scalar curvature is a gravitational invariant on the left-hand side ...

Dark matter is a hypothetical form of matter that is implied by gravitational effects ... is known as the Poisson ...
