Measuring Mass and Volume: Using a Balance

The video tutorial explains how to use a balance to measure the mass of an unknown object, such as a rock. It covers setting up the balance, adjusting the riders to achieve equilibrium, and calculating the total mass by summing the readings on the beams. The tutorial concludes with a brief introduction to using a spring scale.

What are the readings of the riders when the mass of the rock is determined?

What units are used to express the total mass of the rock?
