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 circular motion.
The centripetal force of a skater is affected by the mass of the skater, the speed at which they are moving, and the radius of their circular path.
The speed of the skater has a direct relationship with the centripetal force. As the speed increases, the centripetal force also increases, and vice versa.
The equation for centripetal force is Fc = mv²/r, where Fc is the centripetal force, m is the mass of the skater, v is the speed, and r is the radius of the circular path.
Yes, the centripetal force can be greater than the weight of the skater. This is because centripetal force is dependent on speed and radius, while weight is dependent on mass and gravity. So, even if the skater's weight is less than the centripetal force, they can still maintain their circular motion as long as the other factors are sufficient.
