WHAT IS MATTER?

Physical Science

Chapter 1.1

Objectives:

1. Describe the two properties of all matter.

2. Identify the units used to measure volume and mass.

3. Compare mass and weight.

4. Explain the relationship between mass and inertia.

Matteranything that has mass and takes up space.

Matter in the UniverseEverything in the universe that you can see is

made up of some type of matter.

Matter and Volume Liquid Volume

units ○ Liters (L) & milliliters (mL)

Use Graduated Cylinder○ Read from meniscus

Volume of an Irregularly Shaped Solid ObjectYou can find the volume of an irregularly shaped

object by measuring the volume of water that the object displaces.

Volume of a Regularly Shaped Solid ObjectTo find the volume of a regularly shaped

solid object use the following equation:○ Volume = length width height

LW

H

Matter and Mass The Difference Between Mass and Weight

Weight ○ Measure of the gravitational force exerted on an object.

The more mass an object has, the greater the gravitational force on the object and the greater the object’s weight.

Mass○ The amount of matter in an object

Mass vs. Weight

Mass

•Measure of amount of matter in an object•Always constant for an object no matter where the object is located.•Measure by using a balance.•Expressed in kilograms (kg), grams (g), and milligrams (mg)

Weight

•Measure of gravitational force on an object.•Varies depending on where the object is in relation to Earth (or any large body in the universe.•Measure by using a spring scale.•Expressed in Newtons (N

InertiaTendency of an object to resist a change in

motion. Mass: The Measure of Inertia

An object that has a large mass is harder to move and harder to stop than an object that has less mass.○ The reason is that the object with the large mass has

greater inertia.

Which has more inertia?
