# Gyroscopic Precession

Gryroscopic Precession. We have been collaborating on rotational motion, which is timely for some of the videos I've been doing lately. In this video I talk about gyroscopic precession - the "wobbling" of a spinning top around its axis.

This is caused by the torque due to the object's weight. The big idea is that the torque vector increases angular momentum in the direction of torque. So if there is no angular momentum initially, it will cause the system to swing in such a direction that it is rotating with new angular momentum in the direction of the torque. However, if there was angular momentum to begin with, the torque will change the direction of that angular momentum by causing precession.

## Index of Refraction of Water Experiment

Our goal for this experiment was to find the index of refraction of water. First of all, we had a tank of water and inside a lego toy sitting in the bottom of the tank, then we pointed a laser through air and through the water hitting straight at the toy. In order for us to be able to see the light through the air and water, we used a fog machine and we created a layer of fog around the tank thus making it easier for us to see the light and collect our data.
