WebAug 11, 2024 · By substituting the expressions for centripetal acceleration a c ( a c = v 2 r; a c = r ω 2 ), we get two expressions for the centripetal force F c in terms of mass, velocity, angular velocity, and radius of curvature: (7.6.4) F c = m v 2 r; F c = m r ω 2. You may use whichever expression for centripetal force is more convenient. WebFigure 1. The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve. The second curve has the same v, but a larger Fc produces a smaller r’.
