Dec 16, 2023 · Understand the four basic forces that underlie the processes in nature. One of the most remarkable simplifications in physics is that only four distinct forces account for all known phenomena. In fact, nearly all of the forces we experience directly are due to only one basic force, called the electromagnetic force.

Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity is probably the most intuitive and familiar of the fundamental forces, but it's also been one of the most challenging to explain. Isaac Newton was the first ...
The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another. So, for example, a neutrino that strays close to a neutron can turn the neutron into a protonwhile the neutrino becomes an electron. Physicists describe this interaction through the ...
The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force. And much like gravity, this force can be felt from an infinite distance (albeit the...
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It's 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website. And that's because it binds the fundamental particles of mattertogeth...
The outstanding question of the four fundamental forces is whether they're actually manifestations of just a single great force of the universe. If so, each of them should be able to merge with the others, and there's already evidence that they can. Physicists Sheldon Glashow and Steven Weinberg from Harvard University with Abdus Salam from Imperia...
Oct 20, 2023 · The four forces of nature are the gravitational force, the electromagnetic force, the strong nuclear force, and the weak nuclear force.
Specific kinds of bosons are responsible for three of the fundamental forces of nature — the weak force, electromagnetic force and strong force.
Jul 28, 2020 · The strong force which binds the protons and neutrons in the nucleus of atoms together, and the weak force with is responsible for some kinds of radiation. So how to these forces work? First, all forces, with the possible exception of gravity are mediated by force carrying particles called gauge bosons.
Apr 15, 2023 · Solid carbon dioxide is called dry ice because it does not pass through the liquid phase. Instead, it goes directly to the gas phase. (Carbon dioxide can exist as liquid but only under high pressure.) Dry ice has many practical uses, including the long-term preservation of medical samples. Even at temperatures below 0°C, solid H 2 O will ...

What is a force in physics?
A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces.
