Vertical circular motion is a type of motion where an object moves in a circular path with its center of rotation being in a vertical plane. This means that the object is constantly changing direction and velocity as it moves around the circle.
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 its circular motion.
In vertical circular motion, centripetal force is responsible for keeping the object moving in a circular path and preventing it from flying off in a straight line. Without centripetal force, the object would move in a straight line tangent to the circle.
Centripetal force can be calculated using the formula Fc = mv²/r, where Fc is the centripetal force, m is the mass of the object, v is the velocity, and r is the radius of the circular path.
Some examples of vertical circular motion involving centripetal force are roller coasters, swinging on a playground swing, and a planet orbiting around a star. In all of these cases, an object is constantly changing direction and velocity as it moves in a circular path due to the force of gravity acting as the centripetal force.
