The mathematical formula for mass is mass = density x volume. To calculate the mass of an object, you must first know its density and its volume.Know More
The formula "mass = density x volume" is a variation on the density formula: density = mass ÷ volume. As long as two of the variables are known, the third can be calculated by rearranging the equation. In order to calculate mass, it is necessary to divide both sides of the density equation by volume.
For example, to find the mass of a liter of milk, it is first necessary to know the density of the milk. If the density is 1.03 g/mL, then according to the equation, the mass of one liter of milk is 1.030 kilograms.
Mass is often confused with weight, although they are two different things. Mass is an unchanging quality of an object. Relativistic mass, however, can increase when an object approaches light speed. It is a measurement of the amount of matter the object has. When a physicist discusses the mass of an object, he or she is is talking about the number of particles in the object, not how much they weigh. Weight, on the other hand, is the force of gravity pulling on a mass. The SI unit of mass, as determined by the International System of Units, is the kilogram.
Density is how much mass there is in a given amount of a material. An object of higher density will weigh more than an object of lower density, even if the objects are the same size.Learn more about Measurements
A balance is used to measure mass. By multiplying mass by the acceleration due to gravity, the resulting product is the weight of an object at a specific position.Full Answer >
Anything that has mass and volume is called matter. There are four classical states of matter: solid, plasma, liquid and gas. Each type of matter has different properties.Full Answer >
Mass is the measurement of how much space an object takes up, and weight is the measurement of the pull of gravity on an object. Scientists measure both mass and weight with the use of balances and scales. The formula weight equals mass times gravitational force equates the two measurements.Full Answer >
Mass is a measure of the amount of matter contained by an object, while weight is a measure of the gravitational pull on an object. As the gravitational force exerted by Earth is the constant upon which mass is calculated, the values of an object's mass and weight on Earth are approximately equal depending on geographic location.Full Answer >
