### Centrifugal Force - an overview ScienceDirect Topics

Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis, opposite to the direction of gravity at the equator; at Earth’s poles it is zero. (Centripetal force is the necessary inward force that keeps the mass from moving in a straight line; it is the same …

### What Is the Equation for Centrifugal Force?

Mar 26, 2020 The equation for centrifugal force is F c = mv 2 /r, where m equals the mass of an object, v is the speed and r is the radius, or distance from the center. Centrifugal force is defined as the outward force that an object seems to experience when it moves in a circle.

### What Is the Equation for Centrifugal Force?

Mar 26, 2020 The equation for centrifugal force is Fc = mv2/r, where m equals the mass of an object, v is the speed and r is the radius, or distance from the center. Centrifugal force is defined as the outward force that an object seems to experience when it moves in a circle. Centrifugal force is felt as if it is real but does not technically exist.

### Relative centrifugal force - Big Chemical Encyclopedia

Relative centrifugal force Centrifugation is based on the fact that any object moving in a circle at a steady angular velocity is subject to an outward directed force, F. The F is frequently expressed in terms of the earth s gravitational force and is then referred to as the relative centrifugal force, RCF, or more commonly as the number times g. To be of use, however, these relationships …
