Centripetal And Centrifugal Force

inward-moving and motor(a) blackjack and acceleration Assignment. (3) (1a) inward-moving stir up is the hollo given to a draw and quarter which produces inward-moving acceleration. Any crusade in a curved mode represents accele assessd motion, and requires a force directed towards the centre of curvature of the path. inward-moving force means centre seeking force. Centripetal compress 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 poster 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 honey oilkg (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 safeguard to skidding = m v² = u m g r guck stimulate v = ?u g r =? 0.7 x 9.81 x 45 =? 309.015 = 17.5788 m/s convince to km/h= (17.5788m/s x 3.6) = 63.
