Net Force is the overal force acting on an object. For example, if there is a 10N force acting upwards, and a 5N force acting downwards, then the net force is 5N upwards. A Force is any influence...
Centripetal force is the inward directed force that causes an object to move in a circular path.
Centrifugal force is actually not a force; it is the apparent (and fictitious) "force" that one...
because the difference is, in most cases, the Net Force.
Ex. If an object is at rest (not moving), then it has a net Force equal to 0 Newtons (kg*m/s/s). Fg (force due to gravity) and Fn (Normal...
