Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories ...
The equation for the Law of Universal GravitationOnce, there is a great mathematician and physicist who suddenly think why are there objects like the moon which is not falling. This made him study and proposed the law of universal gravitation. The universal law of gravitation defines that ever...
What is the equation to find the maximum mass an object can hold before it sinks?Answer and Explanation: It really depends what liquid the boat is floating in. Usually, we can assume that the boat is in pure water, and water has a density of 1g/cm^3. You should...
A physics student might encounter gravity in physics in two different ways: as the acceleration due to gravity on Earth or other celestial bodies, or as the force of attraction between any two objects in the universe. Indeed gravity is one of the most fundamental forces in nature. Sir Isaac ...
The conformal noninvariance of the Klein–Gordon equation coupled to a vector potential is confronted with the conformal invariance of Maxwell's equations in the presence of a charged current. The conformal invariance of the nonminimally coupled Klein–Gordon equation to gravity is then examined in ...
Pressure = (density of liquid) x (acceleration gravity) x (height) See more advanced readings about Static Fluid Pressure fromGeorgia State University Physics Dept. If the container is open to the atmosphere above, the added atmospheric pressure must be added if one is to find the total pressu...
So good that we call the constant of proportionality, Newton's Gravitational Constant, and write itGN, or justG. In equation form I would write the gravitational forceFbetween two objects asF = Gm1m2/r^2, where m1 and m2 are the two masses, and r is the distance between their centers....
Momentum (p) is closely linked to speed (v) through the equation: p=mv so the object gains momentum throughout its fall. The mass of the object doesn't affect how quickly it falls under gravity, but massive objects have more momentum at the same speed because of this rel...
General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matter curves the spacetime. ...
The equation for the gravity between many objects is just the equation for the gravity between every pair added up. Not much more complicated. The whole point of physics, aside from understanding things, is to describe the rules of the universe as simply as possible. To that end, physicists...
