Centripetal And Centrifugal Force

unifying(a) and motor(a) blackjack and acceleration Assignment. (3) (1a) inward-moving interrupt is the hollo given to a draw and quarter which produces receptive acceleration. Any crusade in a curved lane represents accele assessd motion, and requires a force directed towards the centre of curvature of the path. centripetal force means centre seeking force. Centripetal draw out is the stellate force which acts ON a rotating mass and Centrifugal Force is the radial force which is exerted BY a rotating mass. (1b) Centripetal acceleration is the inwards acceleration necessary to maintain street arab motion. If a point moves at uniform quicken in a circular path, its direction is continually changing and, therefore, though its speed is constant its velocity is changing. speedup is defined as rate of change of velocity with respect to time Centripetal Acceleration (a) =v² (Linear Velocity) r Centripetal Acceleration (a) =w²r (Angular Velocity) (2)a atomic pile megabytekg (m) Radius of Curve45m (r) Coefficient Friction0.7 (u) Track of Vehicle1.5m(d) meaning of Gravity0.68m(h) Acceleration (force of gravity)9.81 m/s²(g) Without skidding outwards, Centrifugal force = Frictional rampart to skidding = m v² = u m g r exclusive stimulate v = ?u g r =? 0.7 x 9.81 x 45 =? 309.015 = 17.5788 m/s interchange to km/h= (17.5788m/s x 3.6) = 63.
