How exactly does gravity work? - Physics Stack Exchange
Jun 4, 2014 · Physicists believe that the particle for gravity (called graviton) does exist, it's just they haven't found it yet. Standard Model doesn't have gravity, but extended Standard Model …
How does gravity work underground? - Physics Stack Exchange
The other answers provide a first-order approximation, assuming uniform density (though Adam Zalcman's does allude to deviations from linearity). (Summary: All the mass farther away from …
What is the relationship between gravity and inertia?
Gravity - Same dip (curve) due to mass (energy) of the body manifests as gravity for other bodies. So, their origin is same and that is curving of space. Inertia is nothing but gravity of the body …
How does a gravity car work (and where does the energy come …
Dec 21, 2017 · Gravity does work on the falling block, which then does work on the car (through some gearing). We could detail it a bit more and say that the block actually does work on the …
Does gravitational force do work onto an object being lifted?
Jun 24, 2021 · In this case, gravity takes the energy you supply the object and stores it as gravitational potential energy of the earth-object system. The difference in magnitude between …
Does gravity exist in a vacuum? - Physics Stack Exchange
Apr 19, 2015 · The absolute vacuum does not exist, other than "theoretically." Using the practical and conventional definitions for vacuum, the answer to the question is yes, gravity exists in …
What is Gravity and How Does it Work? - Facty
Jan 10, 2020 · The Latin word gravitas means weight and gives us the word "gravity," which is the force that gives objects their weight. It is also the root of "gravitate," a word that describes …
From where does gravity get its energy to do work upon an object?
Nov 17, 2016 · For an object or force to do work, it needs energy. But, from where does the gravitational force get the energy to do work upon, say, a falling object? The gravitational force …
Why does gravity have a stronger effect on objects with more mass?
May 16, 2021 · It does. But your terms are horribly imprecise which probably affects your thinking about it. "Move" doesn't mean anything. More mass = more force applied by gravity but more …
Does gravity matter when calculating work done horizontally?
Nov 9, 2018 · The work done moving horizontally has to be equal to the force in the horizontal direction times the horizontal distance through which the force acts. But you still might ask, …
