摘要:

A sphere, on one side of an Atwood machine, is immersed in glycerin and permitted to fall. We timed the descent and measured the terminal speed. We varied the massm2on the other side of the Atwood machine and plotted a graph of the terminal speed versus massm2. Both the slope and the intercept yield the viscosity.
