What is Centrifugal Force

　・In Japanese

■What is centrifugal force?

Centrifugal force is a force that acts in the opposite direction from the center on an object in rotational motion. Centrifugal force is proportional to the square of the speed and inversely proportional to the distance from the center, and can be expressed by the following formula. In other words, the faster the speed, the stronger the centrifugal force, and the farther the distance from the center, the weaker the centrifugal force. For example, a car driving straight down a road can be considered to be infinitely far from the center of a circle, so the centrifugal force is 0.

There is also the term centripetal force. While centrifugal force is a force that acts from the center outward, centripetal force is a force that acts toward the center of a circle. Rotational motion is possible as a result of the balance between centrifugal force and centripetal force, so the magnitude of both values ​​is equal.
