... When two bodies interact, the forces on the bodies from each other are always equal in magnitude and opposite in direction. For every "action" force, there is always an equal and opposite "reaction" force; we call these a "third-law force pair." •When a table supports an object against the force of ...

... disturbances of the same kind overlap, the resultant amplitude at any point in the region is the algebraic sum of the amplitudes of each contributing wave. The Principle of Superposition leads to the phenomena known as interference. For example, assume that there are two monochromatic and coherent l ...

... A force does positive work when it has a vector component in the same direction as the displacement, and it does negative work when it has a vector component in the opposite direction. The force does zero work when it is perpendicular to the displacement. ...
