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 may have. …
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 what gravity …
From where does gravity get its energy to do work upon an object?
Nov 17, 2016 · 5 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 is …
newtonian gravity - Clarification on work and Gravitational potential ...
Dec 21, 2024 · 2 I’m an 8th grader, and I was studying work and gravitational potential energy (GPE) out of curiosity. I thought about the idea that when I lift an object, the work I do increases its GPE, but …
How does gravity overpower a vacuum? - Physics Stack Exchange
Jun 14, 2024 · how does gravity hold on to Earth's atmosphere up on the fringes of space where it is weaker and against a far more powerful vacuum Note that at sea level, pressure is a lot higher than it …
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 force to …
How does gravity escape a black hole? - Physics Stack Exchange
Dec 16, 2014 · If you think of gravity as a repelling forces then it makes sense that gravity doesn't need to "escape" from a black hole. What fails to escape is the force that repels matter which makes the …
How does gravity do work to a horizontal projectile?
Sep 6, 2023 · 1 In the very first instant of its travel, when the ball's path is horizontal, gravity does no work on the ball. However, after this first instant the ball's motion is no longer horizontal, and gravity …
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 the …
How does a gravity car work (and where does the energy come from)?
Dec 21, 2017 · 2 So I am doing an experiment with gravity car, basically dropping a hanging mass and spins the axle using a pulley system. And then I thought although the work formula W=Fd doesn't …
