Understanding Mass and Weight

What is the primary difference between mass and weight?

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

• Mass is constant, while weight varies with location.

• Mass changes with gravity, while weight remains constant.

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

Which of the following best describes mass?

• The amount of space an object occupies.

• The weight of an object on Earth.

• A measure of an object's resistance to change in motion.

• The force exerted by gravity on an object.

How is weight defined in physics?

• The density of an object.

• The amount of matter in an object.

• The force of attraction between two objects with mass.

• The volume of an object.

What unit is used to measure weight?

• Newtons

• Joules

• Grams

• Kilograms

What is the formula used to calculate weight?

• F = mc

• F = ma

• F = mg

• F = mv
