Twists, turns, thrills and spills: the physics of rollercoasters
WebAug 14, 2021 · A unit that might make purists wince, the G-force is the difference between the acceleration, a, that you experience as a rider and the acceleration due to gravity, g, (9.8 m/s 2) divided by g and expressed per unit mass: (a–g)/g.This force comes into play thanks to the movement you undergo on the ride– you experience a “positive” G-force when the train is at the bottom of a hill, and ...

The spin of a proton – Physics World
WebJun 4, 2015 · At stake is the intrinsic angular momentum, or “spin”, of a proton. Spin is a quantum-mechanical property, akin to the angular momentum of a classical sphere rotating on its axis, except it comes in discrete units of integer or half-integer multiples of ħ. The proton, like the electron and neutron, has a spin of ħ /2, or “spin-1/2”.
The Casimir effect: a force from nothing – Physics World
WebSep 1, 2002 · The Casimir force is the most famous mechanical effect of vacuum fluctuations. Consider the gap between two plane mirrors as a cavity ( figure 1 ). All electromagnetic fields have a characteristic “spectrum” containing many different frequencies. In a free vacuum all of the frequencies are of equal importance.
