tsentrifuugjõu

Tsentrifuugjõud, more commonly known as centrifugal force in English, is not a true force in the Newtonian sense but rather an apparent force experienced by an object moving in a circular path. It arises from inertia, the tendency of an object to resist changes in its state of motion. When an object is forced to move in a curve, such as a circle, a centripetal force must be applied towards the center of the circle to continuously change the object's direction. From the perspective of an observer rotating with the object, it appears as though an outward force is pushing the object away from the center. This perceived outward force is what is termed centrifugal force.

This effect is often observed in everyday situations. For instance, when a car turns a corner, passengers inside feel pushed towards the outside of the turn. This is because their bodies, due to inertia, tend to continue moving in a straight line, while the car is changing direction. The car's tires provide the necessary centripetal force to turn the vehicle. Another common example is a spinning bucket of water. The water is held in the bucket by the inward force from the bucket's bottom, but from the water's perspective, it feels a centrifugal force pushing it outwards. If the bucket spins fast enough, this outward push can overcome gravity, preventing the water from falling out.

The magnitude of this apparent centrifugal force depends on the mass of the object, the square of its velocity, and inversely on the radius of the circular path. It is crucial to distinguish centrifugal force from centripetal force. Centripetal force is a real force directed towards the center of rotation, responsible for maintaining circular motion, whereas centrifugal force is an inertial effect observed in a rotating frame of reference.
