Density, Mass and Weight

Which statement best describes the relationship between the weight and mass of an object?

• If mass increases, weight will decrease.

• Doubling mass reduces weight by half.

• An increase in mass will not affect weight.

• If mass increases, weight will increase.

The gravitational pull on planet A is greater than on planet B. Which of the following best describes the mass and weight of an object that goes from planet A to planet B?

• The mass and weight will be the same on both planets.

• The mass will change, but weight will be the same.

• The mass will be the same, but weight will change.

• Both the mass and the weight will change.

A spring scale is used to measure weight. Which of the following does it measure?

• The force of gravity acting on an object

• The amount of matter in an object

• The composition of an object

• The average density of an object

The table provides data on the pull of gravity on different planets compared to Earth. On which planet would a 70-kg person have the greatest weight?

• Mercury

• Mars

• Jupiter

• Neptune

What happens to the mass and weight of an object that is launched into space, where the pull of gravity is less?

• The mass decreases while the weight stays constant.

• The mass stays constant while the weight decreases.

• The mass increases while the weight decreases.

• The mass stays constant while the weight increases.

Weight and mass are related but different properties. If the mass of Earth were to double, the mass of an object on Earth would remain the same. What change would we expect to see in the weight of an object?

• The weight would decrease by 100%.

• The weight would be reduced by half?

• The weight would double.

• The weight would increase four times.

Nicolas is preparing a solution and needs to measure the mass of some copper sulfate for a solution. As opposed to a spring scale that measures weight, which of the following objects should Nicolas use to measure the mass?

• Electric scale

• Ruler

• Balance

• Graduated cylinder

Jennifer is explaining the difference between weight and mass to her little sister. In comparing the two, which of the following could Jennifer use to correctly describe the weight of an object?

• Weight is the same everywhere in space.

• Weight is how much matter is within an object.

• Weight is the amount of gravitational pull on an object.

• Weight is not impacted by the force of gravity.

Weight and mass are both properties of matter and have a relationship with each other. Increasing the mass of an object on Earth will have which effect on the weight of that object?

• The weight will decrease proportionately.

• The weight always remains the same.

• The weight will increase proportionately.

• The weight always increases twice as much as the mass.
