Notes: Center of Mass
We also completed this short qualitative lab:
Choose at least 3 different cardboard pieces. Sketch them in your lab notebook and qualitatively find their centers of mass. Write a brief description of your procedure and mark the COM on your sketches in your notebook.
Your book does not have many problems involving only the center of mass, so I had to make up a problem. Your homework is:
1.A uniform meter stick has a mass of 0.20kg.
a)Where is its center of mass?
b)A
0.30 kg mass is taped to the meter stick at the 80 cm mark. Now where is the
COM of the system?
