Mass, Weight, Volume, & Density

Front

What is the formula to calculate density?

Back

Density = Mass / Volume

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and does not change regardless of location. Weight is the force exerted by gravity on that mass and can change depending on the gravitational pull.

Front

How do you measure the volume of a regular-shaped object?

Back

Volume = length (l) x width (w) x height (h) for regular shapes.

Front

What is the unit of measurement for density?

Back

Common units for density include grams per cubic centimeter (g/cm³) and kilograms per cubic meter (kg/m³).

Front

If an object has a mass of 20 grams and a volume of 5 mL, what is its density?

Back

Density = 20 g / 5 mL = 4 g/mL.

Front

What happens to the weight of an object if it is taken to the Moon?

Back

The weight decreases because the gravitational pull on the Moon is less than on Earth.

Front

What is water displacement and how is it used to find volume?

Back

Water displacement is a method to find the volume of an irregular object by measuring how much water it displaces when submerged.

Front

If two objects have the same volume but different masses, which one is denser?

Back

The one with the larger mass is denser.

Front

What does it mean if an object is more dense than water?

Back

If an object is more dense than water, it will sink when placed in water.

Front

What is the relationship between mass, weight, and gravity?

Back

Weight is the product of mass and the acceleration due to gravity (Weight = Mass x Gravity).
