Centrifugal Force Formula
The following formula is used to calculate the centrifugal force acting on an object.
F = m * v^2 / r
- Where F is the centrifugal force (Newtons)
- m is the mass (kg)
- v is the velocity
- r is the radius
To calculate the centrifugal force, multiply the mass by the velocity squared, then divide by the radius.
In this equation, the velocity is the tangential velocity. However, the angular velocity can be used as well. Instead, use the angular velocity and multiply it by the radius to calculate the tangential velocity. A centrifugal force always acts perpendicular to the motion of an object. This force causes acceleration, also known as angular acceleration.
Centrifugal Force Definition
A centrifugal force is defined as the force acting directly perpendicular to an object in rotational movement.

FAQ
How does centrifugal force differ from centripetal force?
Centripetal force acts towards the center of the circular path, keeping the object in circular motion, whereas centrifugal force is perceived as acting outward from the center of rotation, often considered a “fictitious” force in a rotating reference frame.
Can centrifugal force be felt in everyday life?
Yes, centrifugal force can be experienced in everyday situations such as when turning sharply in a car and feeling pushed outward, or when spinning a bucket of water over your head without the water falling out.
Why is understanding centrifugal force important in engineering?
Understanding centrifugal force is crucial in engineering for designing safe and efficient systems and machines that involve rotational motion, such as centrifuges, rotating machinery, and vehicles, ensuring stability and proper function.
