What is the definition of mass?

• Mass is the measure of how strongly gravity pulls on an object

• Mass is the measure of the amount matter that makes up an object

• Mass is a measure of how much space an object occupies

What is the definition of volume?

• Volume is the measure of how strongly gravity pulls on an object

• Volume is the measure of the amount matter that makes up an object

• Volume is a measure of how much space an object occupies

Why do you weight more on Earth than you do on the moon?

• Because the force of gravity is stronger on Earth

• Because the force of gravity is stronger on the moon

• Because the force of gravity is weaker on Earth

• Because the force of gravity is weaker on the moon

What is the equation for volume?

• Volume = length * width * height

• Volume = length + width + height

• Volume = length / width / height

• Volume = length - width - height

We can find the volume through displacement

• True

• False

How do you use displacement?

• Record the initial volume, place the object, record the final volume, and subtract the initial volume from the final volume

• Record the initial volume, place the object, record the final volume, and multiply the initial volume to the final volume

• Record the initial volume, place the object, record the final volume, and add the initial volume to the final volume

Some ways we can find the volume are...

• By multiplying the length by the width and the height

• By using displacement

• By reading

When reading the volume what is the curved line called?

• Meniscus

• Sclera

• Retina

The equation for density is?

• Density = mass / volume

• Density = mass + volume

• Density = mass * volume

• Density = mass - volume
