What is a physical balance and how does it work?
Understand the Problem
The question is asking for an explanation of how a physical balance works. It highlights its components, their functions, and the principle behind its operation.
Answer
A physical balance measures mass using the principle of moments by balancing an unknown mass against a known mass.
The physical balance is a laboratory instrument used to measure mass by balancing an unknown mass against a known mass using the principle of moments. It consists of a beam with two pans attached, which balances when equal masses are placed in each pan.

More Information
Physical balances are typically enclosed in glass boxes to prevent external factors like air currents from influencing the measurement.
Tips
Ensure the balance is properly calibrated and leveled before use to avoid measurement errors.
