Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. ... The net force on an object changes the object’s motion.

Brian Greene: When we talk about vibration in physics, ... And this set of equations, the equations for what we call simple harmonic motion are the most ubiquitous equations in all of physics.

If equations of motion can be extracted in such cases, this will make it possible to do physics knowledge-based investigations and simulations even for phenomena that has been considered ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.
