kg/m
kg/m2
m4
kg-m2
Answer is Right!
Answer is Wrong!
The correct answer is D. kg-m2.
Inertia is the resistance of an object to any change in its motion. It is measured in kilograms-meters squared (kg-m2). The more mass an object has, the more inertia it has. This means that it will take more force to change its motion.
Option A, kg/m, is the unit of linear density. It is the mass per unit length of an object.
Option B, kg/m2, is the unit of surface density. It is the mass per unit area of an object.
Option C, m4, is not a valid unit of measurement.
