  1. Fizicks 2nd Semester Review

  2. How do you calculate the Gravitational potential Energy? A 60 Kg diver jumps from a 10 m platform. What is their Eg at the top of the platform? 5880 J

  3. What is the formula for calculating the amount of work done to an object? How much work is done must an engine of a car do if it exerts a force of 500 N at a constant speed over a distance of 30 m? 15,000 J

  4. What is the formula for kinetic energy? A 1.5 Kg kitten is standing on top of a 2 m high fence. The kittens Eg is 29.4 J. Assume all energy is transferred. What is her speed when she hits the ground? 6.3 m/s

  5. What is the work-energy relationship? Hint – look in your unit 1 Energy Notes

  6. What is the formula for calculating the Elastic potential energy? How much elastic potential would be stored in a spring if it was stretched 0 to 0.4 m? (spring constant = 8 N/m) 0.64 J

  7. What is the formula for power? How many joules does your 1600 W blow drier transfer if you dry your hair for 5 minutes? 480,000 J

  8. What is the difference between a transverse and longitudinal wave?What are examples of each? (water/slinky? light? Sound?)

  9. Interference of waves occur in what type of wave? Explain what happens during interference.

  10. What is the difference between a node and anti-node?

  11. What is the Doppler effect?

  12. How do you calculate Doppler effect? You are stopped at a traffic light. An ambulence approaches you from behind with a speed of 18 m/s. The siren produces a sound frequecy of 955 Hz. The speed of sound is 343 m/s. What is the frequency you hear? 1007 Hz

  13. What is a sonic boom?

  14. What is the average hearing range? What is it measured in?

  15. In what mediums can sound waves travel? Light waves?

  16. If one frequency is 450 Hz and the beat frequency is 5 Hz. What are the two potential second frequencies? What is a beat frequency? 445 or 455 Hz Hz

  17. Do you know how to use this chart? R Y G M C B If your answer to that question is No, ASK someone how to use it. It will help you on the final exam!

  18. When we see an object as red, what is really happening?

  19. What are the primary colors of light?

  20. Why are large bodies of water greenish blue?

  21. If I shine red light on a blue board, what color would it appear?

  22. What does the law of reflection tell us about incident and reflected angles?

  23. If you have two plane mirrors set up at a certain angle, how can you determine the number of images without counting all of them?

  24. What type of image do you get with a plane mirror?

  25. What does a convex mirror do to light rays? Converge or diverge?

  26. What does a concave mirror do to light rays? Converge or diverge?

  27. What does a diverginglens do to light rays?

  28. What does a converginglens do to light rays?

  29. How does the Radius of Curvature (C) relate to the focal point (f)?

  30. What are the lens and mirror equations and what do the variables stand for?

  31. What type of particle flows in an electrical current?

  32. What do like charges do with each other & what do opposite charges do with each other?

  33. How does something become positively and negatively charged?

  34. What does the term polarized mean?

  35. What is the difference between charging by induction and conduction?

  36. What are the unit of…CurrentResistanceVoltagePowerEnergy

  37. What is the formula of Ohm’s Law? What voltage is applied to a 4.0 Ω resistor if the current is 1.5 A? 6 V

  38. What is the formula for electronic power? A car battery causes a current of 2.0 A through a lamp. It produces 12 V across it. What the power used by the lamp? 24 W
