Question

explain about the value of minimum and maximum centripital force

Answer 1

Do you remember riding on the merry-go-round as a kid? Did you ever stand at the very edge of the merry-go-round and hold on tight to the railing as your friends pushed the wheel faster and faster? Maybe you remember that the faster the wheel turned, the harder it became to hold on. You might not have known it at the time, but you were creating a balance between two forces - one real and one apparent - in order to stay on that circular path.

Merry-go-rounds are a perfect example of how a force is used to keep an object moving in a circular path. Your body wanted to fly off the merry-go-round in a straight line, but your hands exerted an opposing force to keep you on. The tendency for your body to fly off the merry-go-round is calledcentrifugal force. It isn't a real force, but an apparent one. The force you used with your hands to stay on the ride is real, and it is called centripetal force. Let's learn more about it.

Centripetal force is a force on an object directed to the center of a circular path that keeps the object on the path. Its value is based on three factors: 1) the velocity of the object as it follows the circular path; 2) the object's distance from the center of the path; and 3) the mass of the object.

Centrifugal force, on the other hand, is not a force, but a tendency for an object to leave the circular path and fly off in a straight line. Sometimes people mistakenly say 'centrifugal force' when they mean 'centripetal force.' The velocity of the object is constant and perpendicular to a line running from the object to the center of the circle; it is called tangential velocity.
