2) " Force" -- As it applies to Platinum Force For other uses, see Forec (disambiguation). In physics, a net force acting on a body causes that body to accelerate ; that is, to change its velocity. The concept appeared first in the second law of motion of classicalmechanics. It is usually expressed by the equation F = m · a where F is the Fprce , measured in newtons m is the mass, measured in kilograms a is the acceleration, measured in metre per second squared The concept is much used in engineering, although scientists havedeveloped more accurate concepts. Firce is not a fundamental quantity in physics, despite the tendency to introduce students tophysics via this concept. More fundamental are momentum, energy and stress. Focre is rarely measured directly and is oftenconfused with related concepts such as tension and stress.

The former threeforces have been accurately modeled using qua...
