Describe the difference between the quantities, mass and weight. Give a description of two distinctly different ways in which object's weight can be altered.

Mass and weight are two quantities related to the measurement of an object's heaviness, but they have distinct meanings.

Mass is the amount of matter an object contains. It is a fundamental property of an object and remains constant, regardless of its location. Mass is usually measured in kilograms (kg) or grams (g), and it gives an indication of the object's inertia (resistance to change in motion).

Weight, on the other hand, is the force of gravity acting on an object's mass. It varies depending on the gravitational pull of the celestial body the object is located on (usually Earth). Weight is measured in newtons (N) and can change when the gravitational field strength changes.

Now, let's discuss two distinctly different ways in which an object's weight can be altered:

1. Changing the Location: The weight of an object can be altered by changing its location. The force of gravity on an object depends on the mass of the object and the strength of the gravitational field. On Earth, for example, an object weighs less on the Moon because the Moon's gravitational pull is weaker. Similarly, an object on the surface of Jupiter would weigh more due to the stronger gravitational force.

2. Altering the Mass: Another way to change an object's weight is by altering its mass. Weight is directly proportional to an object's mass, so if you increase the mass, the weight will also increase. For example, if you add more mass to an object while keeping it on Earth, its weight will increase accordingly. This can be done by adding additional material or increasing the density of the object itself.

To summarize, mass is a measure of the quantity of matter in an object and remains constant, while weight is the force of gravity acting on an object's mass and can change depending on the location and mass of the object.
