About previous Physics post/answer from Bobpursely

So do you mean to say....Ferris wheels use motors, therefore meaning that electrical energy is present. Electrical energy from the motor is then turned into kinetic energy. Electricity, generated from a switch and wires, travel through the motor which makes a magnetic field. In the copper coils and the magnet, there is already a magnetic field. So when the two magnetic fields come together, that makes the rotor rotate - which moves the Ferris wheel.

And then, on another note, other types of energy are gravitational potential energy, which is the energy stored in the wheel...so what am I missing here (sorry if this seems dumb, I have so many assignments in physics all at once, that things are a little jumbled, I WANT to understand everything :) )

Again, thanks, much appreciated!

  1. You have it. Friction of course is present, and squeeks and grinding noises, those are energy.
