The inertial mass of an object determines its acceleration in the presence of an applied force. According to Isaac Newton's second law of motion, if a body of mass m is subjected to a force F, its acceleration a is given by F/m
Inertial mass (which leads to momentum) is a measurement of a body's resistance to a change in velocity when an external force is applied to that body.

In physics, mass (from Ancient Greek: ยต??a) commonly refers to any of three properties of matter, which have been shown experimentally to be equivalent: inertial mass, active gravitational mass and passive gravitational mass.
In everyday usage, mass is often taken to mean weight, but in scientific use, they refer to different properties.
Mass is the amount of matter or substances in a body.
Mass is a scalar quantity
SL unit for mass is kilogram
The mass of an object can be measured using:
