Mass and Weight The mass of an object is a fundamental property of the object; a numerical measure of its inertia; a fundamental measure of the amount of matter in the object. Definitions of mass often seem circular because it is such a fundamental quantity that it is hard to define in terms of something else.

In physics, mass is a property of a physical body. It is the measure of an object's resistance to acceleration (a change in its state of motion) when a net force is applied. It also determines the strength of its mutual gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).

what is the difference between mass and weight? Try this exercise! Shown below are two types of scales commonly used in the classroom --a spring scale (left) and a simple balance beam scale on the right.

Mass is defined as the amount of matter an object has. One of the qualities of mass is that it has inertia As an example of inertia, imagine an ice puck resting on a frozen pond. It takes a certain amount of force to set the puck in motion. The greater the mass the more force will be needed to move the puck. The same is true if the puck were sliding along the ice.

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume. Index

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

The quantity of matter in a body. The inertial mass is the mass as a measure of resistance of a body to changes in its motion, and the gravitational mass is the mass as a measure of the attraction of one body to another. The general theory of relativity shows inertial and gravitational mass are equivalent.

Mass is a measure of how much inertia an object shows. The weight of an object on earth depends on the force of attraction (gravity) between the object object and earth. We can express that force as an equation:

where F is the force of attraction, M is the mass of the earth, m is the mass of the object, and r is the distance between the center of mass of the two objects (G is called the Gravitational Constant)
