Mass is a fundamental property of matter that quantifies the amount of substance in an object. It is typically measured in kilograms (kg) in the International System of Units (SI). Mass is a scalar quantity, meaning it has magnitude but no direction.
Mass is often associated with the object's resistance to acceleration when a force is applied, according to Newton's second law of motion (F = ma, where F is force, m is mass, and a is acceleration). The greater an object's mass, the greater the force required to change its motion.
In addition to its role in mechanics, mass also plays a key role in gravitational interactions; objects with mass attract each other, and the strength of this attraction depends on the masses involved and the distance between them, as described by Newton's law of universal gravitation.
It's important to note that mass is distinct from weight, which is the force exerted on an object due to gravity and depends on the local gravitational field strength.
