Which of the following statements are true of the quantity weight?

A person could reduce their weight significantly by taking an airplane ride to the top of Mount Everest.

False - A trip from sea level to the top of Mount Everest would result in only small alterations in the value of g and as such only small alterations in a person's weight.

The weight of an object can be measured in kilograms.

False - By definition, a free-falling object is an object upon which the only force is gravity. Such an object is accelerating at a rate of 9.8 m/s/s (on Earth) and as such cannot be experiencing a balance of forces.

When a chemistry student places a beaker on a balance and determines it to be 84.3 grams, they have weighed the beaker.

False - This student has determined the mass of the beaker, not the weight. As such, he/she has massed the beaker, not weighed it.

To gain weight, one must put on more mass.

Kinda True (Mostly False) - Weight is the product of mass and the acceleration of gravity (g). To gain weight, one must either increase their mass or increase the acceleration of gravity for the environment where they are located.

Two objects of the same mass can weigh differently.

Mostly True - Two objects of the same mass can weigh differently if they are located in different locations.

The weight of an object would be less on the Moon than on the Earth.

True - The weight of an object depends upon the mass of the object and the acceleration of gravity value for the location where it is at.

The weight of an object is dependent upon the value of the acceleration of gravity.

True - The weight of an object is equal to the force of gravity acting upon the object. It is computed by multiplying the object's mass by the acceleration of gravity (g) at the given location of the object. If the location of the object is changed, say from the Earth to the moon, then the acceleration of gravity is changed and so is the weight. It is in this sense that the weight of an object is dependent upon the acceleration of gravity.

The weight of an object is equal to the force of gravity acting upon the object.

True - This statement is the precise definition of weight. Weight is the force of gravity.

Weight refers to a force experienced by an object.

True - This statement is true in the sense that the weight of an object refers to a force - it is the force of gravity.
