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

The mass of an object is variable and dependent upon its location.

False

An object would have more mass on Mount Everest than the same object in the middle of Lake Michigan.

False - An object has the same mass on Mount Everest as it does at sea level (or near sea level); only the weight of the object would be slightly different in these two locations.

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

False - Mass is independent of the gravitational environment that an object is in and dependent solely upon the number of atoms in the object and the type of atoms (Carbon: ~12 g/mol; Hydrogen: ~1 g/mol ; Oxygen: ~16 g/mol).

The mass of an object can be measured in pounds.

False- Mass is measured in Kilograms

If all other variables are equal, then it would require less exerted force to stop a less massive object than to stop a more massive object.

True - A less massive object has less inertia and as such would offer less resistance to changes in their velocity. For this reason, a less massive object requires less force to bring from a state of motion to a state of rest.

The standard metric unit of mass is the kilogram.

True - Know this one. Kilograms is for mass and Newtons is for force.

The mass of an object is mathematically related to the weight of the object.

True - The weight of an object is the mass of the object multiplied by the acceleration of gravity of the object. Mass and weight are mathematically related by the equation: Weight (or Fgrav) = m•g

Mass depends on how much stuff is present in an object.

True - This is kind of a simple definition of mass but it does do the job (provided stuff means atoms or material).

People in Weight Watcher's are really concerned about their mass (they're mass watchers).

True - Weight Watcher's participants only use a measurement of their weight as a reflection of how many atoms of flesh that they have burned from their bodies. Their real interest is in losing mass

If all other variables are equal, then an object with a greater mass would have a more difficult time accelerating.

Weight and force of gravity are synonymous terms.
