   Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. [1] The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg).

   Mass can never be zero. Weight can be zero. As in space if no gravity acts upon an object, its weight becomes zero. Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well. Mass is commonly measured in kilograms and grams.

   What is the difference between mass and weight?

   • Mass is a measure of how much matter an object contains, while weight is the force exerted by gravity on that mass. Essentially, weight is the product of mass and the acceleration due to gravity. This means that an object’s weight changes depending on where it is in the universe, but its mass remains the same.

   What is the basic unit of mass?

   • The basic unit of mass in the International System of Units (SI) is the kilogram (kg). Other units include grams (g), milligrams (mg), and metric tons. In the United States, mass is often measured in pounds (lb), although this is a unit of weight. The distinction between mass and weight is crucial.

   How is mass determined in physics?

   • The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.
