Rotational motion is heavily involved in creating a working Ferris Wheel. Rotational motion involves force, velocity and acceleration.
Newton’s First Law of Motion, also known as the Law of Inertia, states that objects naturally resist a change to their motion. Objects at rest want to STAY at rest, just like objects that are in motion want to stay in motion. In order to overcome the resistance to change in motion, Newton's First Law is important to consider. Especially when you're considering ways to maintain the rotational motion of your Ferris Wheel.
By applying Newton's Second Law of Motion, Force = Mass x Acceleration, you are giving the rotation the force and the acceleration that it relies on. A force is needed to make it move (Newton's First Law), and the amount of force required is calculated using Newton's Second Law.
Newton’s Third Law is not a main component, but it has some importance in the design process. You need to ensure that you centripetal force is balanced out by an equal and opposite force from the objects you are spinning in your Ferris Wheel, otherwise, if the carts on the outside don't contain enough weight, it could collapse to the center. If the outside factors exert a force greater than the inward centripetal force of the Ferris Wheel’s center, for example--if spun too quickly and the wheel suddenly stops, the objects (aka the people on the ride) will fly right off! So you incorporate Newton's Third Law when considering what the maximum speed of the ride needs to be.
