Background & Lab Introduction
Angular momentum is the rotational momentum of an object. An example of angular momentum is a ball rolling down a hill, like in this experiment. Mass and velocity affect angular momentum.

Methods
For this lab, we used Disk Rolling Down Incline Lab to create three different rolling experiments. One experiment changed the shape of the object. One experiment changed the outer radius of the object. One experiment changed the weight of the object. The purpose of this experiment is to see how each piece influences the angular momentum and final numbers.

Results
Results
Experiment 1: Change in shape (bike tire to filled tire).
Experiment 1: Change in shape (bike tire to filled tire).
A change in tire shape increased velocity.
Experiment 2: Change in radius (100 to 120mm).
Experiment 2: Change in radius (100 to 120mm).
An increase in radius slightly decreases position, time, and velocity.
Experiment 3: Heavier mass (100 to 200kg).
Experiment 3: Heavier mass (100 to 200kg).
A heavier mass slows down the object's velocity.
