The universal law of gravitation describes the force of gravity between two bodies. What does it say about the strength of the gravitational field? How does the size of the object affect the use of the gravitational field eq...
When you deal with massive bodies like the Earth, however, which has a mass of 6 x 1024 kilograms (see How much does planet Earth weigh?), it adds up to a rather powerful gravitational force. That's why you're not floating around in space right now. The force of gravity acting on ...
That said all of the above only brings us to our current understanding.Gravity still remains one of the biggest mysteries of physics and the biggest obstacle to a universal theory that describes the functions of every interaction in the universe accurately.If we could fully understand the mechanics...
The Standard Model of particle physics, which describes the actions of almost all known particles and forces, leaves out gravity. While light is carried by a particle called a photon, physicists have no idea if there is an equivalent particle for gravity, which would be called a graviton. ...
The vertical distance from the crest of a wave to the trough is called? What is the pattern of a single high tide and a single low tide daily called? What term describes water that is deposited on the Earth's surface? Which ocean zone has the greatest temperature variation w...
the gravitational force on the pumpkin; m is the mass of the pumpkin; a is the acceleration of the pumpkin. So if I measure the acceleration of the pumpkin, and I measure the mass of the pumpkin (let's leave aside how you do that), then I know the force of gravity on the pumpkin...
One major problem with our current physics is that researchers can't integrate quantum mechanics, which describes how physics works on a very small scale, and gravity, which governs large-scale physics. The rules for how matter behaves at the small scale depend on probability and quantized, ...
I can’t find a good intuitive reason why orbits are elliptical. In fact, I can’t even find a mathematical derivation. So, because it should be found somewhere, I’ll leave the derivation floating in the answer gravy. Answer gravy: The force of gravity is usually wri...
The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. Also known as "Big G" orG, the gravitational constant was first defined byIsaac Newtonin his Law of Universal Gravitation formulated in 1680. It is one...
