Centripetal force is a force that acts on an object moving in a circular path, directing it towards the center of the circle around which it is moving. This force is necessary to keep an object moving in a curved path, as it constantly changes the direction of the object's velocity without changing its speed. The centripetal force is always perpendicular to the velocity of the object and is responsible for keeping the object in its circular motion.
Centripetální síla je síla, která je potřebná k udržení objektu v pohybu po kruhové dráze. Je zaměřena směrem ke středu kruhu a je rovna hmotnosti objektu násobené čtvercem jeho rychlosti dělené poloměrem kruhu.
