2. Matter
Anything that has mass and takes up space
Examples:

3. 4 General Properties of Matter
Density
Mass
Volume
Weight

4. Memory Trick
At the DMV you “Weight”
At the Density Mass Volume you Weight.

5. Mass vs. Weight Mass- the amount of material in an object
Units for mass:
Mass is different form weight because:

6. Mass vs. Weight
Weight- The measure of how hard gravity pulls on an object.
Units for weight:

7. Weight = Mass in Kg x Gravity
Formula for Weight
Weight = Mass in Kg x Gravity

8. Calculating Weight
What is the weight of a desk with a mass of 100 Kg on the planet earth with a gravitational pull of 9.8?
Formula:
Substitute:
Solve:

9. Calculating Weight
What is the weight of a man with a mass of 65 Kg on the planet WAMS which has a gravitational pull of 2?
Formula:
Substitute:
Solve:

10. Volume
The amount of space an object takes up

11. Volume = length x width x height
Volume of a Solid
Formula:
Volume = length x width x height

12. Water Displacement
The method of measuring volume of irregularly-shaped objects

13. Water Displacement Steps of Water Displacement
Pour water into a graduated cylinder. Record the volume of the water.
Place the object in the cylinder. The water level will then rise. Record the new volume.
Subtract the volume of the water from the volume of the water and the object. The difference will be the volume of the object.

14. Units for Volume Units used for a solid: Units used for a liquid
_____________ = ______________

15. Calculating Volume Calculate the volume of the following cube:
Formula:
Substitute:
Solve:
2 cm
5 cm
10 cm

16. Calculating Volume
A graduated cylinder has been filled with 35 mL of water. A stone is added to the graduated cylinder and the water level rises to 42 mL, what is the volume of the stone?

17. Density
A measurement of how tightly the matter of a substance is packed into a given volume.

18. Density
Formula for Density:
Mass
Volume
Density =

19. Density
Magic Triangle of Density

23. Solve for Density
If you have a metal bar that has a mass of 57.9 g and a volume of 3 cm3, what is the density of the metal bar?
Formula:
Substitute:
Solve:

24. Solve for Volume
If you have a block bar that has a mass of 99.0 g and a density of of 3 g/cm3, what is the volume of the metal bar?
Formula:
Substitute:
Solve:

25. Solve for Mass
If you have a rock that has a density of 20 g/cm3 and a volume of 3 cm3, what is the mass of the rock?
Formula:
Substitute:
Solve:
