    • Exploring Physical Science Chapter 1, Section 1
    • Science
      • A process of gathering knowledge about the natural world.
    • What is Physical Science?
      • The study of matter and energy.
        • Matter is the “stuff” that everything is made of.
          • Shoes, pencil, air
          • Energy is the ability to do work.
            • NRG is partly responsible for rainbows, but is not the rainbow itself.
            • All moving objects and non-moving objects have energy.
            • Food has NRG that is xferred to you.
    • Physical Science Branches
    • Chemistry
      • Looks at the structure and properties of matter.
        • Different substances behave differently under the same conditions.
        • Chemistry is also the study of how substances change.
          • Chemical reaction takes place when one substance reacts w/ another substance to make a new substance.
    • Physics
      • Studying different forms of NRG is what Physics is all about.
        • Motion, force, gravity, electricity, light, and heat are parts of physics.
          • Riding a bike and using your brakes
            • Force causes motion
    • Which of the following statements is true?
      • NRG is the ability to do work.
      • Air is made of matter.
      • All matter has NRG.
      • All of the above.
    • What is the difference between Chemistry & Physics?
    • Answer:
      • Chemistry is mainly the study of the properties and interactions of matter. Physics is mainly the study of forces and motion.
