What type of balance features unlike objects on either side of an imaginary?

A balance that features unlike objects on either side of an imaginary line is known as a "seesaw" or "lever balance." This type of balance operates on the principle of moments, where the weight and distance from the fulcrum determine equilibrium. It illustrates how different weights can achieve balance when positioned correctly relative to the pivot point. Such balances are commonly used in educational settings to demonstrate fundamental principles of physics.
