Transcript

• 1. What is Matter?
Physical Science
Chapter 1.1
• 2. Objectives:
Describe the two properties of all matter.
Identify the units used to measure volume and mass.
Compare mass and weight.
Explain the relationship between mass and inertia.
• 3. Matter
anything that has mass and takes up space.
Matter in the Universe
Everything in the universe that you can see is made up of some type of matter.
Baseball
Red blood Cells
Milky Way Galaxy
• 4. Matter and Volume
Liquid Volume
units
Liters (L) & milliliters (mL)
• 5. Volume of an Irregularly Shaped Solid Object
You can find the volume of an irregularly shaped object by measuring the volume of water that the object displaces.
• 6. Volume of a Regularly Shaped Solid Object
To find the volume of a regularly shaped solid object use the following equation:
Volume = length  width  height
H
L
W
• 7.
• 8. 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
• 9. Mass vs. Weight
Mass
• Measure of amount of matter in an object
• 10. Always constant for an object no matter where the object is located.
• 11. Measure by using a balance.
• 12. Expressed in kilograms (kg), grams (g), and milligrams (mg)
Weight
• Measure of gravitational force on an object.
• 13. Varies depending on where the object is in relation to Earth (or any large body in the universe.
• 14. Measure by using a spring scale.
• 15. Expressed in Newtons (N
• 16. Inertia
Tendency 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?
