Centrefugal force is a fictitious force that appears to act on objects in circular motion. It is not a real force, but rather an apparent force caused by an object's inertia.
Centrefugal force works by pulling objects away from the center of rotation and towards the outer edge of the circular path. This is due to the object's inertia, or tendency to continue moving in a straight line, even as the path curves.
Centrefugal force and centripetal force are often confused, but they are actually two different forces. Centripetal force is the real force that keeps an object in circular motion, while centrefugal force is the apparent force that seems to pull objects away from the center of rotation.
Centrefugal force is used in many applications, such as amusement park rides, centrifuges in laboratories, and even in sports like figure skating and roller skating. It is also a key concept in understanding the rotation of planets and other celestial bodies.
Centrefugal force can be calculated using the formula F = mv^2/r, where F is the centrefugal force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular path. This formula shows that centrefugal force increases with mass, velocity, and the size of the circular path.
