Moment of force.<\/p>\n<p>A moment of force, also called torque, is a force that causes rotation. It is calculated by multiplying the force by the distance from the axis of rotation. The greater the force or the greater the distance, the greater the moment of force.<\/p>\n<p>Centripetal force is a force that acts towards the center of a circle. It is necessary to keep an object moving in a circular path. The centripetal force is equal to the mass of the object times the square of its velocity divided by the radius of the circle.<\/p>\n<p>Centrifugal force is an apparent force that acts away from the center of a circle. It is not a real force, but rather an illusion created by the inertia of the object. The centrifugal force is equal to the mass of the object times the square of its velocity divided by the radius of the circle, but in the opposite direction of the centripetal force.<\/p>\n<p>The center of gravity is a point where the entire weight of an object can <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> be considered to be concentrated.
