What is the mass of an object?<end_of_turn>
<start_of_turn>model
The mass of an object is a fundamental property that reflects the amount of matter contained within it. Unlike weight, which can vary based on the force of gravity, mass is a constant quantity and does not change regardless of location or gravitational force. 

Mass is typically measured in kilograms (kg) or grams (g) in the metric system, and in pounds (lbs) in the imperial system. It's a measure of an object's resistance to acceleration when a force is applied, and it also determines the strength of its gravitational attraction to other bodies. 

In physics, mass is a crucial concept and is involved in laws of motion and gravitational theory. For example, Newton's second law of motion states that force is equal to mass times acceleration (F = ma), highlighting the role of mass in determining how an object will move when a force is applied to it. Similarly, in the law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses.<end_of_turn><eos>
