If you swing an object on a string around in a circle, you can feel the effects of the centripetal force through the tension in the string. As the object moves in a circle, it constantly pulls on the string, creating tension in the direction towards the center of the circle. This tension in the string is a result of the centripetal force acting on the object, causing it to continuously change direction towards the center of the circle. Therefore, the feeling of tension in the string is an indication of the centripetal force acting on the object.
