Question

mission nl6: mass vs. weight
which of the following statements are true? select all that apply.
a. on earth, more massive objects weigh more than less massive ones.
b. the mass of an object on the moon will be the same as its mass on earth.
c. the weight of an object on the moon will be the same as its weight on earth.
d. the weight of an object is its mass multiplied by the force of gravity.
e. the mass and weight of an object are the same thing.
f. the mass of an object is the force of gravity acting upon an object.

Explanation:

• a. On Earth, gravity is constant, so weight $W=mg$ means more mass leads to more weight.
• b. Mass is an intrinsic property, independent of location.
• c. Moon's gravity is weaker than Earth's, so weight differs.
• d. Weight is defined as the gravitational force on mass: $W=mg$.
• e. Mass is an intrinsic property; weight is a force, so they are not the same.
• f. This defines weight, not mass. Mass is the amount of matter.

Answer:

a. On Earth, more massive objects weigh more than less massive ones.
b. The mass of an object on the moon will be the same as its mass on Earth.
d. The weight of an object is its mass multiplied by the force of gravity.
