Question

Distinguish between Mass and Weight.

Hint:

Mass is always constant, while weight changes with location due to variations in gravitational force.

Answer 1

Mass: Mass is a measure of the amount of matter in an object. It is a scalar quantity and is typically measured in kilograms (kg) or grams (g). Mass does not change regardless of the object's location in the universe. 

Weight: Weight is the force exerted by gravity on an object. It is a vector quantity and depends on both the mass of the object and the gravitational acceleration. The formula for weight is: \[ \text{Weight} = \text{Mass} \times \text{Gravitational acceleration} \] Weight varies depending on the location of the object (for example, on Earth, weight is measured in newtons, while it would be less on the Moon). - Mass is an intrinsic property of matter, meaning it remains constant regardless of the object's location. - Weight depends on the local gravitational field. For instance, an object weighs less on the Moon due to weaker gravity than it does on Earth.
