1. Centrifugal force
It does not exist!

2. Centrifugal Force
An object traveling in a circle behaves as if it is experiencing an outward force.

3. Centrifugal Force
This force depends on the mass of the object, the speed of rotation, and the distance from the center. The more massive, the greater the speed or the greater the distance the object, the greater the force from the center, the greater the force.

4. Centrifugal Force
However, centrifugal force does not actually exist.

5. The Real Force
According to Newton's first law of motion, a moving body travels along a straight path with constant speed (i.e., has constant velocity) unless it is acted on by an outside force. For circular motion to occur there must be a constant force acting on a body, pushing it toward the center of the circular path.

6. Centripetal Force
This force is the centripetal (“center-seeking”) force.

7. Centripetal Force
A constant force acting on a body, pushing it toward the center of the circular path.

8. Centripetal Force
For a planet orbiting the sun, the force is gravitational; for an object twirled on a string, the force is mechanical; for an electron orbiting an atom, it is electrical

9. Centripetal Force
The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path.
F=mv2/r
F = force, m = mass, v = velocity and r = radius of travel

10. Gyroscopes
A device for measuring or maintaining orientation, based on the principle of conservation of momentum.

11. Gyroscopes
The spinning device tends to resist changes to its orientation due to the angular momentum of the wheel. In physics this phenomenon is also known as gyroscopic inertia or rigidity in space.

12. Gyroscopes
A gyroscope exhibits a number of behaviors including precession.
Precession is a change in the direction of the axis of a rotating object.
