What is relationship between mass and inertia? Give the SI unit of mass and inertia.
Mass and inertia are correlated. Mass of a body is a measure of its inertia. Both of them are directly related. More massive is the body, larger is the inertia or opposition offered by a body to change its state of motion.
SI unit of mass is kilogram (kg)
SI unit of inertia is kilogram (kg)
