A physics question
posted by Nessa on .
I was researching amusement park rides for a recent project (from this site I have noticed that many others are in the same boat as me). Anywho, I am doing the Ferris wheel or the Giant Wheel, and I was wondering if this was right, with respect to potential energy: this is due to the wheels vertical position; this type of energy does not change on the Ferris wheel as it revolves, if gondolas on the are the same mass, because the center of mass does not change . The center of mass is single point at which the entire mass of a body is considered to be concentrated. The ferris wheel's center mass is its center. This point acts a balance point for the wheel so, the potential energy remains the same at all points on the Ferris wheel. The potential energy is calculated by PE=mgh or mgd
I am pretty sure that this right, but if you could please verify, that would be wonderful! Danke!
Yes it is right. Potential energy has very little to do with hiow ferris wheels work. It is mainly a case of electrical energy makng the motor do work overcoming bearing friction. Kinetic energy is not a factor either, except when it is starting up.
