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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and stays constant regardless of location. Weight is the force exerted by gravity on that mass and can change depending on the gravitational pull.

Front

What is mass?

Back

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

Front

What unit is used to measure mass?

Back

The unit for measuring mass is grams (g) or kilograms (kg).

Front

What does a balance scale measure?

Back

A balance scale measures mass.

Front

What happens to weight as you move away from Earth?

Back

Weight decreases as you move away from Earth due to the reduction in gravitational pull.

Front

What is the formula for calculating volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is the unit of measurement for volume?

Back

The unit for measuring volume is cubic centimeters (cm³) or liters (L).

Front

How do you find the volume of an irregular object?

Back

You can find the volume of an irregular object by using the water displacement method.

Front

What is the relationship between mass and density?

Back

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

Front

What is the weight of an object with a mass of 10 kg on Earth?

Back

Weight = mass × gravity; Weight = 10 kg × 9.8 m/s² = 98 N (Newtons).
