In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own ...

Physicists use the displacement formula to find an object's change in position. It sounds simple, but calculating displacement can quickly get complicated. Let's break it down using some solved ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. I'm teaching introductory Newtonian mechanics again this term, and as ...

The most powerful formula in physics starts with a slender S, the symbol for a sort of sum known as an integral. Further along comes a second S, representing a quantity known as action. Together, ...

Mathematical equations aren't just useful — many are quite beautiful. And many scientists admit they are often fond of particular formulas not just for their function, but for their form, and the ...

Albert Einstein proposed the most famous formula in physics in a 1905 paper on Special Relativity titled Does the inertia of an object depend upon its energy content? Essentially, the equation says ...
