Why do we feel lighter and heavier at the highest and lowest points of a Ferris wheel? Suppose, the Ferris wheel is revolving with a constant angular velocity. |

Answer» Solution :At the highest point of the WHEEL, we have, MG - n = `(mv^(2))/(r )` where m = mass of the PASSENGER, v = linear velocity of the passenger at the ROTATING Ferris wheel, r = radius fo curvature of the Ferris wheel and n is the normal reaction. `therefore "" n = mg - (mv^(2))/(r )` So, we FEEL lighter at the highest point. At the lowest point of the trajectory, n - mg = `(mv^(2))/(r)"" or, n = mg + (mv^(2))/(r)` Hence, we feel heavier at the lowest point of the Ferris wheel. |
