Before I finish my epic math quest, is this what you are looking for? So, using the right-hand rule, the vector for rotational momentum points up along the gyroscope's axis. Now, when gravity tries to rotate the gyroscope, it also has to rotate the rotational momentum vector. Because gravity...

Perfect! Thanks so much!

It seems to me that one could argue that the concept of a coefficient of restitution doesn't work here because if the percent loss is constant for a material, then, because the duration of the collision is variable depending on masses and velocities, the instantaneous energy loss would also have...

So, I've decided that the way to answer this question is to completely solve the gyroscope problem without using vector operations. This will take quite a while, but should make sense. First I'm going to idealize the gyroscope: it has a stationary massless frame which contacts the pivot...

Here is my conceptual understanding of the gyroscope: Imagine a spinning gyroscope sitting at an angle on top of a rod. Now freeze time. The lower side of the gyroscope is being pulled DOWN by the torque of gravity around the axis of the gyro, and so that point on the gyro will gain downward...

Hi, I am trying find equations for continuous "stretchy" collisions, in other words, I have two perfectly round objects of known mass, radius, and velocity, and want to collide them and be able to have them squish together and then bounce apart. I am aware of the method of solving for the...
