Name: _____________________________________________ Period: ____ Date: _______________ IPS Mid-term Exam Study Guide DAY 4 Tips for reviewing for your exam: 1. Have your notes available and organized. We have covered all the topics below, and you should be familiar with the location of the information that you need to study. 2. Log onto Jason.org and review the missions that we covered. Look specifically at the topics highlighted below in the guided questions. The missions may even help you answer the questions! 3. Read; don’t skim your notes and answers! You will have to recall quite a bit of information, so going over it once is not enough! 4. Remember to include your units in your answers when you are asked to calculate. Remember, the units identify the quantity; units show you know what you are talking about. On separate loose-leaf paper, answer the following questions. 1. What is energy? THE ABILITY TO DO WORK 2. Explain the difference between potential energy and kinetic energy. PE IS STORED ENERGY, KE IS ENERGY IN MOTION 3. List the different types of potential energy. Give an example of each NOT from your textbook. 4. List the different types of kinetic energy. Give an example of each NOT from your textbook. 5. Thing about your lab using the balloon, string and straw (the lab where you launched the balloon across the room when attached to the straw threaded on the string). What happens to the balloon if you blow it up more before you release it down the string? What type of energy is stored in the inflated balloon? What happens to that energy when you release the balloon? PE WHEN AIR INSIDE BALLOON, KE WHEN IT IS RELEASED 6. Read page 18 of Infinite Potential. What is the difference between infrared electromagnetic energy and ultraviolet electromagnetic energy? Which one was sunscreen developed to protect humans from cancer? UV 7. We read about CME’s and how they can potentially affect the Earth. What are CME’s and how do scientists detect CME’s? How can CME’s potentially cause damage on Earth? COSMIC MICROWAVE EMISSIONS, SUNSPOT ACTIVITY, BLACKOUTS 8. Review pages 20 and 21 of Infinite Potential. Describe two risks and two benefits to using high-energy radiation. RISKS – DANGEROUS IN HIGH DOSES, BENFEIT SUCH AS MRI OR X-RAYS 9. Explain the difference between energy transfers and energy transformation. Give examples of each. Be able to identify different types of energy transfers and energy transformations. Think of the RubeGoldberg machines! TRANSFER = SAME FORM OF ENERGY, TRNASFORMATION = CHANGE IN FORM OF ENERGY Name: _____________________________________________ Period: ____ Date: _______________ 10. What is the Law of Conservation of Energy? Give an example of an energy transformation where energy is totally conserved in an ideal situation (in other words, no friction, no energy loss). ENERGY CAN NOT BE CREATED NOR DESTROYED ONLY TRANSFERRED OR TRANSFORMED … ROLLER COASTERS 11. Think of your Coaster Creator Lab. The top of the first hill describes the total energy of the system. Describe in terms of potential energy, kinetic energy and energy dissipation why the roller coaster eventually comes to a halt. TOP = POTENTIAL FASTEST PART = KINETIC END = DISSIPATED TO HEAT 12. Define the following: a. crest = TOP OF A WAVE b. trough = BOTTOM OF A WAVE c. compression = LONGITUDINAL WAVE COMPRESSED d. rarefaction = LONGITUDINAL WAVE STRETCHED e. wavelength = MEASURE OF CREST TO CREST OR TROUGH TO TROUGH OF WAVES f. amplitude = HEIGHT OF A WAVE FROM REST 13. What is the difference between a compression wave and a transverse wave? THEIR MOVEMENT (LOOK AT IMAGES) 14. What is a medium? How are mediums related to waves? SUBSTANCE THROUGH WHICH WAVES TRAVEL 15. Describe how waves travel in solids, versus liquids and gases. Why is the speed different in each state of matter? FASTER IN SOLIDS DUE TO COMPACT PARTICLES 16. Describe the energy transformations that take place when a tsunami forms. POTENTIAL TO KINETIC OF MOVING LAND MASS 17. Explain why astronauts cannot hear explosions in outer space? (In other words, what makes it possible for humans to hear sound?) NO MEDIUM TO TRAVEL THROUGH
