Building a Mass Balance to Measure Small Weights Using a Rotary Potentiometer

Establish mass balance for measuring small weight using rotary potentiometer Introduction: Today, there are mass balance, weighing scale, etc. for measuring quality, but there are few instruments for measuring small mass . Sometimes, we may need to measure small quality objects like 10 g to 100 g, and my model is created with this idea. Components used: digital multimeter, gauge rule, distillation stand, clamp, rotary potentiometer, power supply (5 V), spring, mass (10 g), 2 k and 3 k resistors, 1 k variable resistor, amplifier.

The basic SI mass unit is kilogram (kg). In physics, rather than directly comparing the known mass and the equilibrium ratio, the quality is usually different from the mass, even if the mass is determined by measuring the mass of the object using the spring balance. Because of the low gravity, the moon's celestial body is smaller than the earth's weight, but it is still the same quality. This is because the weight is the force and the mass is the characteristic (with gravity) that determines the strength of the force.

Gram is a unit used to measure quality. Quality is a measure of the quality of an object in an object. Quality and weight are different. Weight is a measure of gravity. Because there is no strong gravity, you lose weight of the moon. On the other hand, quality is the same everywhere in the universe. The mass is measured with a balance. One balance is a two pot balance that functions like a seesaw. Quality is a measure of the quality of an object in an object. Both biological and abiotic are composed of substances. The problem has quality and space. Most substances on Earth have three states: liquid, solid, and gas. All substances are composed of small particles called atoms. Atoms are the smallest units of substances that can exist and are still recognized. Everything around you and everything is made up of problems.

Quality is a measure of the amount of substance in a substance. The balance can be used to measure the mass of an object. To determine the quality of an object, that object is compared with another object of known quality. The unit of measurement that scientists use to measure mass is kilogram (kg) or gram (g). Volume is a measure of the amount of space an object occupies. The volume can be measured in various ways. In the case of liquid, you can measure the volume using a cylinder. To obtain the volume of a rectangular parallelepiped, multiply it by length, width, and height (v = l × w - h). Volume is measured in liters or cubic such as cubic meters. Cubic meters are cubes with sides of 1 meter.
