Every object on this earth, every substance that you see, can be described and measured by physical properties, like hardness, color, or malleability, odor, length, or temperature, or these magic three.
Mass, volume, and density, three physical properties, mass, volume, and density.
Hey everybody, my name's mass, I'm the amounts of matter in a solid or a liquid or a gas.
My unit is the kilogram, the more force it takes to move me, the more massive I am.
And let's get this straight, mass is not the same as weight, I stay constant.
As for me, I change depending on gravity.
Mass, volume, density, three physical properties, mass, volume, density.
I am volume, call me V, the space that something takes up, that's me.
Tiny as a teardrop, large as the skies, or something in between, I'm a measure of size.
Milliliters, or cubic centimeters, either way, I am 3D space.
A cool way to find me, drop a thing in water, how much water does it displace?
Mass, volume, density, three physical properties, mass, volume, and finally, density.
I'm density, how tightly packed your molecules are, like people in a subway car.
Are they close or are they far?
Density, I'm density, does something float in the air or sea?
If the object has less density, it floats, buoyancy.
Maybe I have buoyancy.
What's our connection?
Excellent question.
We are related like a family.
If you know two of us, you can find the other.
D equals M divided by V, yeah, D equals M divided by V.
