to simply put, multiplication was used in the given (6.67)(2.25) = 15.0075 move the decimal point to the left (once) and you get 1.5 usually answers are expressed like these examples: • 1.0 • 2.5 • 7.8 and use exponents to shorten big numbers therefore, 1.5x10^-10N i suggest you look up scientific notation so you can get a better understanding :))

The origin of momentum creation is founded on the application of energy. Momentum serves as the initial cause of pushing and pulling. The energy, emanating from the internal core of a planet, is what gives rise to momentum, commonly referred to as gravity, and not due to the planet’s size, mass, or space-time curvature. For example, when energy is applied, it generates the necessary momentum for the actions of pushing and pulling. Without the application of energy, momentum cannot be established. Consequently, force cannot be exerted for pushing and pulling, as it lacks a physical existence. This, in turn, clarifies why force is not gravity. ~Guadalupe Guerra

Actually in the perfect round revolution gravity is taken out, the newton intuition and explanation is half right half wrong. The force of gravity cancels out in the formula. In an elliptical revolution the condition of falling and missing fits better, but again just in the falling pathway. Isn't it?

Haven’t found it yet, but back in the day I used to know it, the gravitational formula on the face of the earth. There is no such thing as a true ‘center of gravity’ outside a singularity. On the face of the earth, one is pulled mostly straight down, but also at angles. Was hoping this video pointed that out.

g is the average density of mass. it's actually a wave of probability dependant on the frequency of quantum interactions required to contain energy as mass. the time required for each interaction. relative to the time of its souroundings. movement of mass over the same distance at less speed. requires less force. so mass with excess energy moves faster time. mass that looses energy. moves towards slower time. a unified theory of gravity.

Makes so much sense! But then what happens when a rocket is traveling perpendicularly away from the earth toward the moon, not accelerating but moving at a constant speed? Is there a small gravity toward the bottom or engines of the rocket since this is in the direction of the earth? At some distance weightlessness should balance between the pull of the moon and earth. I imagine there’s a name for this equilibrium point in space

Sierra Ok, so i know its pretty late to answer for now, but just in case I wanted to help since this has been stumping me as well. So remember the formula wheras F1=F2= G M1 x M2/ distance or radius ^ 2, you have to square the radius or distance and then divide it by the numerator's product. It seems really insignifcant but it makes all the difference. Hope you or anyone else can find help from this :3

The formula might lead you to believe that the gravitational force would be infinite, but nothing could be further from the truth. This formula is only strictly true for point masses. You can prove with Calculus that it applies for spherically symmetric masses of any size and distance as long as they are external to each other, with that last phrase being the key point. It only applies when the bodies are external to each other. If you consider something in the center of Earth, you'd have to add up the gravity due to every piece of Earth as vectors, because Earth is not a point mass. Given a spherically symmetric world, at the exact center of it, the gravitational force adds up to zero. So you would be weightless in the center of Earth.

a easy way to find gravity is to drop something and see how far it moves. a way to confirm the measurement is to devide a distance of 1 by 3 to find the difference between begining middle and end. make a circle out of two of them and find the radius of that circle. thats gravity.

As I've been trying to learn about gravity, it seems to me that the gravitational constant calculation is flawed. It does not factor in the force used to lift the weight of the ground and that's the same problem I find with the 9.8 meters per second figure. It doesn't factor in the forced used to lift the objects either. You can't have a Mic drop if nobody actually picks it up and let's it go.
