Centripetal force is the force that keeps an object moving in a circular path. It is always directed towards the center of the circle and is necessary for an object to maintain a curved motion.
The formula for calculating centripetal force is F=mv²/r, where F is the force, m is the mass of the object, v is the velocity, and r is the radius of the circle.
Some examples of centripetal force in everyday life include the moon orbiting around the Earth, a car turning around a curve, and a roller coaster moving around a loop.
Yes, centripetal force can be greater than the weight of an object. This is because centripetal force is dependent on the velocity and radius of the circle, not the weight of the object.
Centripetal force is a result of Newton's First Law of Motion, which states that an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force. In the case of circular motion, the centripetal force is the external force that keeps the object moving in a curved path.
