Mass Study Guide

What is Mass?

Mass is a measure of the amount of matter in an object. It is a fundamental property of an object that determines the object's resistance to acceleration when a force is applied.

Units of Mass

The standard unit of mass in the metric system is the kilogram (kg). In the imperial system, mass is commonly measured in pounds (lb) or ounces (oz).

Measuring Mass

Mass can be measured using a balance scale or a digital scale. The mass of an object is usually determined by comparing it to known masses or by using a calibrated scale.

Calculating Mass

The mass of an object can be calculated using the formula:

Mass = Density × Volume

Importance of Mass

Mass plays a crucial role in various scientific fields, including physics, chemistry, and engineering. Understanding mass helps in determining an object's inertia, gravitational force, and energy requirements for motion.
