# Mass (m)

The mass of an object is a measure of its resistance to acceleration. The higher the mass of an object, the more force is required to achieve a given level of acceleration. The SI unit of mass is the kilogram (kg). What is mass in short answer? Mass is a measure of the amount of matter in an object. It is usually measured in grams (g) or kilograms (kg).

##### What is mass in definition?

One of the most common definitions of mass is "the amount of matter in an object." In other words, mass is a measure of the amount of material that makes up an object. This definition is often used in everyday conversation, but it can be difficult to apply to objects that are very small or very large.

Another common definition of mass is "the measure of an object's resistance to acceleration." This definition is more technical, but it can be easier to apply to objects of all sizes. This definition is also more accurate, since it takes into account the fact that an object's mass can change depending on its speed.

The SI unit of mass is the kilogram (kg).

### What is the unit of mass?

The unit of mass is the kilogram (kg). The kilogram is the SI unit of mass and is defined as the mass of the International Prototype of the Kilogram (IPK), a platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures (BIPM) in SÃ¨vres, France. What is its mass m in kg? The answer is that its mass m in kg is 9.3.

### Is mass a weight?

There is no universal answer to this question, as the concept of "mass" can be defined in different ways, and in some cases, it may be synonymous with "weight". In general, however, "mass" refers to the amount of matter in an object, while "weight" is a measure of the force exerted by gravity on that object. So, an object with more mass will have more weight, but the two concepts are not the same.
