Bookmark or Share- Does centrifugal force exist? - Physics Stack ExchangeFortunately, there is a trick: you can use a point on the surface of the Earth as your reference and pretend that it's an inertial frame of reference, if you also pretend that some external "imaginary" (fictious) forces exist in addition to the real ones. These are the centrifugal force and the Coriolis force.
- Calculating the Generalized force with and without the lagrangianYou are mixing up concepts from d'Alemberts principle and Lagrangian mechanics.To show you what is wrong we will look at an example which is related to your problem, s.t. you can find out the solution to your problem quite easy afterwards.
- forces - Exchange particles-real or just mathetical constructs ...i have got a theory to unify the 4 forces, but it does not tell anything about exchange particles in case of the weak force.I could proceed only if they are imaginary. The problem with a unified theory of all four forces is not of postulating a unification. It is of embedding in the theory the Standard Model. The SM encapsulates very many data ...
- What is the underlying explanation behind fictitious/pseudo forces?This is the popular explanation as to why pseudo forces are introduced, however no one really touches on to the underlying principles of the occurrence of a pseudo force, so I'm looking forward for a more in depth explanation into the nature of a pseudo force (i.e why it occurs from a physical perspective?), rather than just saying that we ...
- What is the physical meaning of a pure imaginary force?The physical force is not imaginary, it is given by the real part of the expression. That expression is not pure imaginary because each component of ${\bf U}_{\rm tip}$ is itself a complex number here. So its real part (which is the force) will not be zero.
