It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other particle (for instance, the particles of "Earth" and the particles ...
The spin of a heavy object, such as Earth, should twist and distort the space-time around it. In 2004, NASA launched theGravity Probe B(GP-B). The axes of the satellite's precisely calibrated gyroscopes drifted very slightly over time,according to NASA, a result that matched Einstein's ...
Einstein didn't believe gravity was a force at all; he said it was a distortion in the shape of space-time, otherwise known as "the fourth dimension" (see How Special Relativity Works to learn about space-time). Basic physics states that if there are no external forces at work, an obj...
Juggling the concepts of mass, weight, and force is not simple, especially when you try to jump back and forth between two different systems of measurement. In order to understand them you must factor in time, gravity, and distance. While mass, length, and time are absolute qualities, ...

In simple words, it can also be imaginedas the point of rotation of a vessel.Now, since the hull is never a regular-shaped body, this pivot point is never the same as the Centre of Gravity, or C.G of the vessel, about which we have dealt with so much in the entire field of nav...
A strange thing happens in the attraction between two quarks: The strong force does not decrease with the distance between the two particles, as the electromagnetic force does; in fact, it increases, more akin to the stretching of a mechanical spring. As with a mechanical spring, there is ...
The COVID-19 pandemic has revived a decades-old debate about how respiratory diseases travel—which affects the safety practices experts recommend.
It can also integrate well with other transport developments, such ascontainers. Customs-sealed units have enabled frontiers to be crossed with the minimum of delay. Therefore, it increases the speed and efficiency of the shipper. The ship has also proved extremely popular with holidaymakers and pr...
