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 opposite of gravity?Force:The force can be defined as a quantity that applied to the object to change the position of the object or try to change the position of the object. The force applied depends upon the mass of the object and the acceleration of the object. The force...
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 ...
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. ...
Example With Gravity Example With Gravity Astronauts reach a distant planet and find it takes eight times as much force to lift objects there than it does on Earth. What is the acceleration due to gravity on this planet? On this planet the force of gravity is eight times larger. Since the...
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...
