Document Summary

An interaction between two bodies, an object and an agent. Something which can be produced with or w/o contact. Something w/o which there is no acceleration. = we have a good sense of some si units of measure. Length & time we can think in these terms with reasonable comfort. Joules, amps, candelas - maybe not so much. The si unit for force is the newton. A restoring force: the elastic tries to return to its equilibrium con guration. Magnitude of the restoring force is proportional to how much it has been stretched! It a measure of the stiffness of the spring. A diagram that represents all forces acting on an object. Do not draw forces acting on other ojects. Do not draw forces caused by this object. Do not include a force for ma". Draw arrows pointing outward from the object. If the object is moving, but velocity is constant (a =0) Now f=ma, at least in one direction.
