The extra terms in the force F' are the "fictitious" forces for this frame.

As an example, consider a rightward force F of 15 newtons.

Because the potential U defines a force F at every point x in space, the set of forces is called a force field.

Suppose a particle starts at point A, and there is a force F acting on it.

Now suppose the charge is subject to a force F due to other charges.

This force F, parallel to the ground, is greatest when θ is 45 degrees.

The resultant of both the forces is the force F .

A central force F has two defining properties.

The motion of a particle under a central force F always remains in the plane defined by its initial position and velocity.

The force F is generated by the wind interacting with the blade.
