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.
