WebJan 1, 2024 · The model solution writes the components of F such as Fx = -mω2x. To be more specific, the solution quotes the force field . However, all we can conclude from the problem statement is that this force field coincides with the actual force field along a circle of radius . The actual force field may have any other behaviour away from this circle. snl 1982 cast

Exercise 8.1. 1 You push a crate from point A to point B along a horizontal surface. Is the force you exert a conservative force? Yes No Not enough information Answer WebA conservative force is a type of force which serves to transform an object's energy between kinetic and potential. When only conservative forces do work upon an object, the energy of the object changes forms (KE to PE or vice versa) without changing the total amount of mechanical energy.
