Final answer:
Forces acting on the Ferris wheel system include gravity, the normal force, and friction. The angular velocity and angular momentum of the Ferris wheel are affected by these forces.
Step-by-step explanation:
Forces acting on the Ferris wheel system include gravity, the normal force, and friction. Gravity acts vertically downwards and provides the centripetal force needed to keep the Ferris wheel moving in a circular motion. The normal force acts perpendicular to the surface of the Ferris wheel and balances the weight of the people and the wheel. Friction between the axel and the bearings allows for the wheel to rotate smoothly.
When the wheel begins to turn, the angular velocity increases. The centripetal force provided by gravity remains the same, so an increase in angular velocity leads to an increase in angular momentum. The increased angular momentum causes the Ferris wheel to rotate faster.
