Key Terms

● Matter ● Volume ● Meniscus ● Mass ● Gravity ● Weight ● Newton ● Inertia

What is matter?

● Matter is anything that had volume and mass.

Matter has Volume

● All matter takes up space.● The amount of space taken up, or occupied,

by an object is known as the object's volume.○ your fingernails have volume because they occupy

space at the end of your hands.● Because things all have volume, they cannot

share teh same space at the same time.

Liquid Volume

The next time you see a can of soda, youcan read the volume printed on the can. Or you can check the volume by pouring the soda into a large measuring cup.● Volume is measured in liters (L)

Measuring the Volume of Liquids

● The meniscus is the curve at a liquid’s surface by which you measure the volume of the liquid ○ When we measure liquids in a graduated cylinder

Measuring the Volume of Solids

● What would you do if you wanted to measure the volume of your textbook?○ The volume of any solid object is expressed in cubic

units. Remember, cubed means 3.○ The three dimensions for volume are: length, width,

and height ○ We measure length in meters (m)

Math Break (left side)

A typical compact disc (CD) case has a length of 14.2 cm, a width of 12.4 cm, and a height of 1.0 cm. The volume of this case is the length multiplied by the width multiplied by the height:

14.2 cm x 12.4 cm x 1.0 cm = 176.1 cm3

Measuring the Volume of Gases

A gas expands to fill its container. If you know the volume of the container that a gas is in, then you know the volume of the gas.

Day 3

Objective

● I will name the two properties of all matter.● I will describe how volume and mass are

measured.● I will compare mass and weight.● I will explain the relationship between mass

and inertia.

Measuring Mass and Weight Mass is…● A measure of the amount of

matter in an object ● Always constant for an object

no matter where the object is in the universe.

● measured with a balance (see p. 41)

● 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 (or any other large body in the universe)

● measured with a spring scale (p. 41)

● expressed in newtons (N)○ Newtons are the SI unit

of force

Mass Is a Measure of Inertia ● Which do you think would be easier to pick up and throw, a soccer

ball or a bowling ball?○ The difference has to do with inertia (the tendency of all objects

to resist any change in motion)■ because of intertia an object at rest like a soccerball will

remain at rest until something casues it to move.● likewise, a moving object will continue to move at the

same speed and direction unless something acts on it to chage speed or direction.
