It does not require the object to touch, making it a non-contact force.Answer and Explanation: The two things gravitational force depends on are the mass of the two objects that generate the gravitational force and the distance between them. The......
Thus, dark matter's gravitational impact is extremely spread out and, it turns out, can only be observed when we look at the large-scale distribution of visible matter in the universe: things like galactic superclusters and the corresponding super-voids. It's theorized that after the Big Bang...
In order for the speed of light to be constant, even if the light is "launched" from a moving object, only two things can be happening. Either something about our notion of distance and/or something about our notion of time must be skewed. As it turns out, both are skewed. Remember,...
Is there gravitational force in space? What factors determine the gravitational potential energy of an object? The mass of the moon is 7.36 times 10^22 kg and its distance to the Earth is 3.84 times 10^8 m. What is the gravitational force of the moon on the earth?
However, most likely the more important limiting factor was the ability to determine the precise moment at which a perfect half Moon (or new Moon, or full Moon) occurs; this is extremely difficult to do with the naked eye. (The telescope would not be invented for almost two more millennia...
Laser Interferometer Gravitational-Wave Observatory Hanford installation – each arm extends for four kilometres. Credit: Caltech. If a gravitational wave is detected, the two observatories use triangulation to determine its magnitude and direction. At least, that was the plan from 2002 to 2010. The...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
The proton's nucleus-partner, neutrons, serve an important purpose; they keep the protons in the nucleus and determine the isotope of an atom. They're not critical to our understanding of electricity, so let's not worry about them for this tutorial. ...
When Hawking returned home for the Christmas holidays after his first semester at Cambridge, his parents immediately noticed his bizarre behavior and insisted he undergo testing to determine the cause of his strange symptoms. Hawking fell into a deep depression after he was diagnosed with ALS (amyot...
The two things we know for sure about dark matter (assuming it exists), is that it exerts gravity (has mass) and that it moves slowly (compared to the speed of light). How do you look for dark matter? Since we don't know what dark matter is, the answer is: for every possible ca...
