the centripetal force along with the attractive force of the electron on the nucleus are balanced by a phenomnon known as the strong nuclear force which prevents the electron from coliding with the nucleus

In circular motion, the centripetal force is provided by the electrostatic attraction between the positively charged nucleus and the negatively charged electron. This force keeps the electron in its circular orbit around the nucleus. The balance between the centripetal force and the electron's inertia maintains its circular motion.
Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.
The centripetal force on a particle in uniform circular motion increases with an increase in the mass of the particle or the speed at which it is moving. It also increases if the radius of the circle decreases, as the force required to keep the particle in the circular path becomes greater when the circle is smaller.

Centripetal motion refers to the inward force that keeps an object moving in a curved path. This force is always directed toward the center of the circular path. It is responsible for keeping objects like planets in their orbits around the sun.
The inward force needed for circular motion is called centripetal force. It is directed towards the center of the circle and is required to keep an object moving in a curved path instead of a straight line. Without this force, the object would continue in a straight line tangent to the circle.
