Force Diagram Centripetal Force. This is another proof that can be done analytically but i don t want to do it. Centripetal force acts at right angles to the tangential velocity of the particle there is no displacement in the direction of force hence no work is done by centripetal force.
You may do so in any reasonable manner but not in. This outward force should never be shown on a free body diagram because it s not a real applied force to the mass. Figure 6 20 the frictional force supplies the centripetal force and is numerically equal to it.
Centripetal force is perpendicular to velocity and causes uniform circular motion.
Under the following conditions. The second curve has the same v but a larger f c produces a smaller r. The larger the f c f c the smaller the radius of curvature r and the sharper the curve. You may do so in any reasonable manner but not in.
