Gravity pulls stuff down and friction is stopping things from moving. The weight makes it go faster.

I have learned the patterns of motion are made by the stretcher they can have movement by the gravity and friction.  They can move in motion because they use curved paths or they can use the slope that makes a rotational motion. To make the axle or the cup go straight they will also need to be standard.  If you want it standard you need the same size of an axle and you need one shaft but you can use more than one. you can rotate a wheel and axel system by putting one big axle on one side and put a small axle on the other side and there, you can rotate a wheel and axel system.
