# What does a balance measure?

A:

A balance measures the weight of an object or compares the difference of weight between two separate bodies. This measurement of weight can then be converted into mass, hence it is also possible to measure the mass of objects using a balance.

The weight of an object is different than its mass. Weight of an object is equal to the mass of the object times the gravitational pull of the earth. By measuring the weight of an object, its mass is easily calculated. Since the gravitational pull of the earth is always present, it is a convenient practice to measure the weight of any object and then, if necessary, calculate its mass.

Velocity is a measure of the displacement of an object divided by the time it took to travel that distance. Velocity is commonly measured in meters per second, though other units can be used.

The most common way to measure the mass of an object in grams is to use a scale or balance. Techniques vary but are generally similar to measuring weight. In a laboratory setting, more sophisticated measurement instruments such as analytical balances are used.
