Because if there's no force acting on an object, then the object
continues moving with constant speed in a straight line.
Newton made that simple statement a little over 300 years ago,
and nothing in our everyday experience has ever disproved it.

The force is needed to change the direction of the object's velocity, as it constantly points toward the center of the circle, due to the centripetal acceleration required to maintain circular motion. Without this force, the object would move in a straight line tangent to the circle instead of following the circular path.
Centripetal force is the force that keeps an object moving in a circular path. It acts towards the center of the circle and is necessary to maintain the object's trajectory.
The force that keeps an object moving in a circle is directed towards the center of the circle. This force is called the centripetal force and it is responsible for changing the object's direction continuously, keeping it in circular motion.
A centripetal force acts towards the center of the circle, continually changing the object's direction towards the center. This force prevents the object from moving in a straight line and keeps it moving in a circular path.
Yes, to keep an object moving in a circle, a force must be exerted towards the center of the circle. This is known as centripetal force.
The force that accelerates an object towards the center of a circular path is called centripetal force. This force is necessary to keep the object moving in a circle by continuously changing the direction of its velocity. Without centripetal force, the object would continue moving in a straight line tangentially to the circle.
