1. Exploring Physical Science Chapter 1, Section 1

2. Science

• A process of gathering knowledge about the natural world.

3. 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.

4. Physical Science Branches

5. 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.

6. 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

7. 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.

8. What is the difference between Chemistry & Physics?

9. Answer:

• Chemistry is mainly the study of the properties and interactions of matter. Physics is mainly the study of forces and motion.
