Centrifugalkrafter

Centrifugalkrafter, often translated as centrifugal force, is a concept used in physics to describe the apparent outward force experienced by an object moving in a curved path. It's not a true force in the Newtonian sense, meaning it doesn't arise from an interaction between two objects. Instead, it's an effect of inertia. When an object is moving in a circle, its tendency is to continue moving in a straight line due to inertia. To keep it moving in a circle, a real force, called the centripetal force, must be applied towards the center of the circle. The centrifugal force is what an observer moving with the object would perceive as pushing them outwards.

Imagine a car turning a corner. The passengers inside feel themselves pushed towards the outside of the turn. This is the centrifugal force. In reality, the car's steering wheel (and the friction of the tires) provides the centripetal force, pushing the car (and its occupants) towards the center of the turn. From the passenger's non-inertial frame of reference, it appears as if there's an outward force. This apparent force is proportional to the object's mass, the square of its velocity, and inversely proportional to the radius of the circular path. It's a crucial concept in understanding motion in rotating reference frames and is applied in various fields, including engineering and astronomy.
