Reaction (physics)
PART OF NEWTON'S LAWS
Action and Reaction; Action and reaction; Reaction force; Reactive force; Law of action and reaction
As described by the third of Newton's laws of motion of classical mechanics, all forces occur in pairs such that if one object exerts a force on another object, then the second object exerts an equal and opposite reaction force on the first. The third law is also more generally stated as: "To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.
Reaction Records
BRITISH INDEPENDENT RECORD LABEL
Reaction Records was an independent British record label, run by music executive Robert Stigwood in 1966 and 1967. Although Reaction released only three albums, one EP and eighteen singles in its brief existence, its roster included two of the most popular British bands of the time, The Who and Cream.

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.
