8th Grade Unit 6, Lesson 1 Mass, Weight, Volume and Density

Front

What is the definition of mass?

Back

Mass is the amount of matter in an object, typically measured in grams or kilograms.

Front

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

How does density relate mass and volume?

Back

Density is defined as mass per unit volume (Density = Mass/Volume).

Front

Why do ice cubes float in water?

Back

Ice cubes float in water because they are less dense than the water.

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If two objects have the same volume but different masses, how do their densities compare?

Back

The object with the greater mass will have a higher density.

Front

What instrument is used to measure mass?

Back

A balance or scale is used to measure mass.

Front

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

Back

The weight of an object decreases on the Moon due to the lower gravitational force compared to Earth.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming constant gravitational acceleration.

Front

How can you determine the density of an object?

Back

To determine the density of an object, divide its mass by its volume (Density = Mass/Volume).
