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...

The Four Fundamental Forces. Why does Earth stay in orbit around the Sun? How does light travel? What holds atoms and nuclei together? For centuries, scientists have sought to describe the forces that dictate interactions on the largest and smallest scales, from planets to particles.
A fundamental force of nature is an attraction or repulsion between objects as described through interactions between fields and particles. Physics has identified four basic types of these interactions, which together describe every action we see...
