Mass, Weight, Volume, Density Practice

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in grams or kilograms. Weight is the force exerted by gravity on that mass, measured in newtons. Weight changes with gravity, while mass remains constant.

Front

Which measurement changes when moving from Earth to the Moon?

Back

Weight changes because the gravitational pull is different on the Moon compared to Earth.

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³).

Front

How do you determine if an object will sink or float in water?

Back

If the density of the object is greater than the density of water (1 g/mL), it will sink. If it is less, it will float.

Front

What is the formula to calculate the volume of a rectangular object?

Back

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

Front

How do you find the volume of an irregularly shaped object?

Back

You can find the volume of an irregularly shaped object using the water displacement method.

Front

What tool is used to measure mass?

Back

A balance or scale is used to measure the mass of an object.

Front

If 50 mL of water is in a graduated cylinder and the water level rises to 60 mL after adding an object, what is the volume of the object?

Back

The volume of the object is 10 mL (60 mL - 50 mL).

Front

What is the unit of measurement for weight?

Back

The unit of measurement for weight is newtons (N).

Front

What happens to the weight of an object if it is taken to a place with less gravity?

Back

The weight of the object decreases because weight is dependent on the gravitational force acting on it.
