Quick Answer: Physics Mass Comparison Balance is a mechanical balance that finds the mass of an object by matching it against known reference masses on the opposite pan until the beam reaches equilibrium.

Key Features
Mechanical mass-comparison balance
Test object and reference masses go on separate pans
Beam or pointer shows when the two sides balance
Needs no electrical supply
About This Product
After zeroing the empty balance, the object goes on one pan and known masses are added to the other with forceps, using smaller masses as the pointer nears the centre. Because gravity acts equally on both pans, it compares mass rather than weight, a useful point when Applied Mechanics lessons separate the two quantities.
Frequently Asked Questions
Q1. Does the Physics Mass Comparison Balance measure mass or weight? It compares mass. Gravity acts on both sides of the beam, so its effect cancels in the comparison under normal laboratory conditions.
