Physical Science Semester 2 Review
Your final will be over the following chapters from your book: CH 11 Forces, 12 Gravity/Friction/Pressure, 13 Work/Power/Energy, 14 Machines, 5 Atomic Structure/Periodic Table, 6/7 Chemical Bonds/Reactions
You will be allowed to use your triangle sheet, polyatomic ion paper and a periodic table (I will provide).
You should have a general familiarity with all the vocab words from the above units as well. The test will be partially matching/multiple choice and partially free response math problems.
1. List the 5 types of forces.
2. Draw a free body diagram for a ball on a slanted surface leaning against a wall to keep if from sliding down the hill.
3. What are Newton’s 3 laws?
4. What is the acceleration of an object that has a mass of 5 kg when a 10 N force is applied?
5. What is the mass of an abject that is accelerating at 10 m/s 2 when a 6 N force is applied?
6. What is the momentum of a 95 kg football player traveling 2.3 m/s?
7. A box has a weight of 120 lbs and the bottom of the box is 12 in2 . What is the pressure the box exerts on the floor?
8. What is free fall? What is the value used to represent acceleration due to gravity?
9. How much work is done when a force of 33N pulls a wagon 13 meters?
10. Tommy does 15 Joules of work to push the pencil over 1 meter. How much force did he use?

20. Draw and label the genera structure of atom.
21. What is it called if the number of neutrons in an atom changes? When an electron is gained or lost? What happens if a proton is added or lost?
22. What are the names of the major families of the periodic table? What are some properties for each?
23. Where are the metals, nonmetals and metalloids located on the periodic table? How does this impact what types of bonds the elements form?
