Question

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

Explanation:

• a. Incorrect: Mass is an intrinsic property, weight is gravitational force.
• b. Incorrect: Moon has weaker gravity, so weight is less.
• c. Correct: Mass does not change with location.
• d. Correct: On Earth, weight $W=mg$; larger mass $m$ gives larger weight $W$ with constant $g$.
• e. Incorrect: Mass is an intrinsic property, weight is a force.
• f. Correct: Weight is defined as $W = m \times g$, where $g$ is gravitational acceleration.

Answer:

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