Mass varies depending on the location of the object.
Explanation
Mass is a fundamental physical quantity representing the amount of matter contained in a body. It is an intrinsic property of an object and is distinct from weight, which is the force exerted on the object due to gravity.
Statement-wise Analysis:
- Mass is a measure of inertia. is Correct: Mass is defined as the quantitative measure of inertia. Inertia is the property of a body to resist changes in its state of rest or uniform motion.
- Mass varies depending on the location of the object. is Incorrect: Mass is a scalar quantity and remains constant regardless of the location of the object in the universe. It does not change with variations in gravity. In contrast, weight ($W = mg$) varies depending on the acceleration due to gravity ($g$) at a specific location.
- Mass remains constant regardless of location. is Correct: Since mass represents the quantity of matter, it remains invariant whether the object is on Earth, the Moon, or in outer space.
- Greater mass implies greater inertia. is Correct: According to Newton's laws of motion, an object with greater mass has greater inertia. This means a larger force is required to change its velocity compared to an object with lesser mass.
Key Takeaway:
Mass is a constant, intrinsic property of matter and a measure of inertia. It must not be confused with weight, which varies with the strength of the gravitational field.
