Unformatted text preview: motion of an object in a circular direction Fc = FN Sinθ = mv^2/r FNcosθ=mg Tanθ = v^2 / rg On a Ferris wheel NB – mg = mv^2/R => NB = mg + mv^2/R = m (g+v^2/R) Mg – NT = mv^2/R => NT = mg – mv^2/R = m(g- v^2/R) *The Normal force is greater @ bottom giving a greater pressurized force on a person. @ v^2/R = g ; normal force = 0- > 0 weight / weightless (at top) *Walking is considered uniform circular motion: Fcent = mg = mv^2 / g => √gr = v Newton’s Law of Gravitation G = 6.674 x10 ^ - 11 Nm^2 / kg^2 (Gravitational Constant)...
