Permachart - Marketing Reference Guide: Fictitious Force, Body Force, Centrifugal Force
Document Summary
Note: in each situation, the diagram on the left is indicated by the heading of the section (e. g. , weight on frictionless surface); the diagram on the right is the corresponding free body diagram (see force & vector representations) Free weight: w is a force; therefore, it is a vector, this force is due to gravitational interaction between the earth and the body, which always acts towards the center of the. Weight on frictionless surface: rn is the reaction of the floor acting on the stationary weight, in this case, rn = w or action = reaction (newton"s third law) Note: mass is not a force; it is a property of matter and related to weight by w = mg. Weight on frictionless surface with horizontal force: since the mass is being pushed on a frictionless floor, the only resistance to the acceleration is the inertia (ma) of the mass; it opposes the acceleration.
