For the analysis, we will use a moving reference frame attached to the rotating disk. Using this in Newton's 2nd law, we determine the contact force F acting on the particle. It is seen that the ...

Non-contact forces close non-contact forcesA force that affects an object without coming into contact with that object, eg magnetism. are forces that act between two objects that are not ...

Forces are responsible for all the interactions between particles and objects. They can be put into two categories: contact forces and non-contact forces. Forces can be added up as vectors.
