To get to point six at the top you would have to … Webapparent weight depends on the speed, but actual weight is constant. 2) Normal force from the seat points downwards TRUE. As the centrifugal force directed is greater than weight directed downwards, normal reaction is directed downwards. 3) The magnitude of normal force depends on how fast the person is moving TRUE. Normal reaction is given by. WebThe normal varies from a maximum at the bottom of the loop to a minimum at the top. As the motorcycle drives up the loop, the friction force acts along the direction of motion to keep gravity from slowing it down. As the motorcycle drives down the loop, the friction force acts opposite the direction of motion to keep gravity from speeding it up. fly fnl

WebAt the loop’s top, the minimum force required for the ball to just remain in contact with the loop is supplied by gravity without any normal force, so mg = mv2 R (3) (3) → (2) provides: h min = 2.7R (note that this is .7R above the loop’s top). UCI PHYSICS AND ASTRONOMY Lecture Demonstration Program Updated 3/16/09 Procedure: 1. WebAnswer (1 of 2): At top of loop the loop: N+mg=mv^2/R N is zero only when moving at the minimum speed so that the object is not exerting a force on the loop. mg=mv^2/R so min. v=sqrt(gR) If going faster than that, N must exert a downward force so that the centripetal force is N+mg. BTW, mv^2/...
