Forces: associated with deforming objects; stretching and squashing – springs; with rubbing and friction between surfaces, with pushing things out of the way; resistance to
motion of air and water.
Forces measured in newtons, measurements of stretch or compression as force is changed.
Force-extension linear relation; Hooke’s Law as a special case opposing forces and equilibrium: weight held by stretched spring or supported on a compressed surface.
