Physical Science 1.1 : What is Matter?

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