Understanding Mass and Weight

What is the primary difference between mass and weight?

• Mass is a measure of force, while weight is a measure of matter.

• Mass is constant, while weight varies with gravity.

• Mass changes with location, while weight remains constant.

• Mass is measured in Newtons, while weight is measured in kilograms.

What is the mass of an object a measure of?

• The volume of the object.

• The density of the object.

• The amount of matter in the object.

• The gravitational force on the object.

How does Natalie's weight change when she is on Mars compared to Earth?

• It increases because Mars has more gravity.

• It remains the same because her mass is constant.

• It decreases because Mars has less gravity.

• It becomes zero because Mars has no gravity.

What unit is used to measure weight as a force?

• Joules

• Newtons

• Pounds

• Kilograms

Why is mass a better measure than weight for comparing objects in space?

• Because weight is more consistent.

• Because weight is zero in space.

• Because mass is easier to measure.

• Because mass changes with gravity.

What happens to Natalie's mass when she is in deep space?

• It becomes zero.

• It increases.

• It decreases.

• It remains the same.

How does the gravitational force affect weight?

• It causes weight to increase.

• It has no effect on weight.

• It causes weight to decrease.

• It determines the weight based on its strength.

What happens to the weight of an object as it moves away from a planet?

• It increases.

• It remains constant.

• It decreases.

• It becomes negative.

What is the relationship between atomic mass and atomic weight?

• Atomic weight is a measure of force.

• They are used interchangeably but refer to the same thing.

• They are completely different concepts.

• Atomic mass is always larger than atomic weight.

Why do scientists sometimes use the term 'atomic weight'?

• Because it is more accurate than atomic mass.

• Because it is easier to calculate.

• Because it measures gravitational force.

• Because it is a traditional term.
