1. What is Matter?
Chapter 2 Section 1

2. Matter What do all of these objects have in common?
These objects all have volume and mass.
Matter - is anything that has volume and mass

3. Matter has Volume
Volume – the amount of space that something occupies or the amount of space that something contains
An object’s volume is the amount of space the object take up
Objects with volume can’t share the same space at the same time

4. Measuring Volume of Liquids
Meniscus – the curve at a liquid’s surface by which you measure the volume of a liquid
To measure volume correctly, read the scale at the lowest part of the meniscus at eye level.
Show them.

5. Measuring Volume of Solids
Expressed in cubic units (m3 or cm3)
Cubic means “having three dimensions”

6. Comparing Solids and Liquids
You are able to compare liquids and solids because 1mL = 1cm3

7. Measuring the Volume of Gas
Gas expands to fill its container, of if you know the volume of the container the gas is in, then you know the volume of the gas.

8. Matter has Mass
Mass – is the amount of matter that something is made of.
Gravity – is a force of attraction between objects that is due to their masses.
All matter has mass, therefore all matter experiences gravity

9. Let check out what
Tim and Moby
have to say about
Gravity!!

10. Gravity
Gravitational force is large between objects with large masses that are close together.

11. Gravity
Gravitational force is smaller between objects with smaller masses that are close together than between objects with large masses that are close together.

12. Gravity
An increase in distance reduces gravitational force

13. Weight
Weight – a measure of the gravitational force exerted on an object
Newton (N) – the SI unit of force

14. The Difference Mass is: Weight is:
A measure of the amount of mater in an object
Always constant for an object no matter where the object is in the universe
Measured with a balance
Expressed in Kilograms (kg), grams (g), and milligrams (mg).
Weight is:
A measure of the gravitational force on an object
Varied depending on where the object is in relation to the Earth
Measured with a spring scale
Expressed in newtons (N)

15. Inertia
Inertia – the tendency of all objects to resist any change in motion
An object at rest will remain at rest until acted on
An object moving will remain moving at the same speed and direction unless something acts on it to change its speed or direction.
Inertia increases as mass increase
