How does mass bend space-time? That is to say: How does mass create gravity? The answer is the famous Einstein equation of gravity. We explain them in plain language. This is possible, because nature has chosen the law of gravity to be as simple as possible. We will see that basically...

the moon, some 400000 km away, wouldn’t revolve around us constantly. It is the gravity in space that keeps Neptune rotating around the Sun, and what keeps the Sun glued to our galaxy. Gravity is a force that exudes from mass, which, I’m sure, can be found everywhere in the Unive...
How does the force of gravity depend on the mass of two objects? What will the acceleration be if the force and the object's mass are both halved? How to work out formula mass How is weight calculated from the acceleration due to gravity?
Also, microgravity does some interesting things to fire. When you strike a match here on Earth, gravity pulls cool, dense air downwards as hot gasses rise up — resulting in a teardrop-shaped flame. But on the ISS, flames take the form of tiny bluish spheres. These have already revolution...
That's why we need to look at Einstein's later theory, theGeneral Theory of Relativity, which describes how gravity affects the shape of space and flow of time. Imagine a stretched-out sheet. If you place a bowling ball in the middle of the sheet, the sheet will warp as the weight ...
There are two ways in which sand can become agitated enough to create quicksand: Flowing underground water: The force of the upward water flow opposes the force of gravity, causing the granules of sand to be more buoyant. Earthquakes: The force of the shaking ground can increase the pressure...
For 𝑛=0n=0, it has 𝐺(𝑥)=(𝜗1+𝑔)𝑥G(x)=(ϑ1+g)x, and the dry mass gain increases linearly with the size of the plant, which, like the previous case, does not represent reality. (c) For 𝑛>1n>1, if 𝑥≫1x≫1 then 𝐺(𝑥)=𝜗𝑔1𝑥(𝑛−...
[2]. This test should incorporate various drop heights to assess at what height the athlete can elevate more his centre of gravity, and it was already proven to be a reliable and valid test to measure the RSI [3]. The RSI can be calculated by dividing the jump height by the ground ...
to put the bar on and off your back. You use the adjustable safety pins to catch the bar if you fail to Squat the weight back up. The bar moves freely so you decide where it goes and Squat using a natural movement. You balance the weight which builds more strength andmuscle mass. ...
