What is M1 and M2 in gravitational force?

m1 and m2 are the masses of the two things being attracted, in your case, the moon with a mass of 7.347 x 1022 kg, and some other mass (in kg) and the distance between the masses, in meters.

What happens to the gravitational force between the two objects when the distance between them is doubled?

So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).

Does gravitational potential decrease with distance?

The trick is that gravitational potential energy actually increases with distance. This value increases from a large negative value to a small negative value as the object is moved farther from M until it finally reaches zero at an infinite distance.

Does gravitational potential energy depend on distance?

The gravitational potential energy of an object depends on the mass of objects, and how far away they are from each other. More massive objects have more gravitational pull.

How does G relate to G?

Relationship Between G and g g is the acceleration due to the gravity of any given body in m.s. G is the universal gravitational constant in Nm2.kg.

What is the unit of gravitational potential at infinity?

⇒ Important Points: 1 The gravitational potential at a point is always negative, V is maximum at infinity. 2 The SI unit of gravitational potential is J/Kg. 3 The dimensional formula is M 0 L 2 T -2.

What is the formula for gravitational potential energy at height?

Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. If a body is taken from the surface of the earth to a point at a height ‘h’ above the surface of the earth, then r i = R and r f = R + h then, ΔU = GMm [1/R – 1/ (R+h)] ΔU = GMmh/R (R + h) When, h<

What happens when the gravitational potential energy is zero?

At a point in the gravitational field where the gravitational potential energy is zero, the gravitational field is zero. What is Gravitational Potential? The amount of work done in moving a unit test mass from infinity into the gravitational influence of source mass is known as gravitational potential.

How do you find the gravitational field from an infinite plane?

For the gravitational field due to a uniform infinite plane lamina, all one has to do is to put α = π/2 in equation 5.4.7 or ω = 2 π in equation 5.4.9 to find that the gravitational field is .g = 2πGσ 5.4.13 This is, as might be expected, independent of distance from the infinite plane.
