  1. Which of the following is true of parallel circuits but NOT of series circuits (S8P5) • They provide more than one path for the flow of current • They may use batteries as an energy source • They may include more than one load • They may use switches to control the flow of current PE = mass X height Using the above formula what is the potential energy of a rock with a mass of 50kg that rests at the edge of a cliff 125m high? (S8P3) • 2.5 J • 50 J • 125 J • 6,250 J

  2. Gravitational force depends on (S8P3) • Force • Mass and distance • Mass and direction • Location Which of the following is MOST LIKELY to be attracted to a magnet and then become magnetized itself? (S8P5) • A piece of nickel • Rubber band • Aluminum can • Copper wire

  3. When you strike a match against a matchbox the BEST summary of the energy transformation that takes place is (S8P2) • Chemical energy to thermal energy to light energy • Light and thermal energy to chemical energy • Mechanical energy and thermal energy to light energy • Mechanical energy to thermal energy Electric power is measured in units called • Ohms • Volts • Watts • Amps

  4. What object is most likely to absorb light energy and convert it to thermal energy? (S8P2) • A mirror • A sheet of white paper • A black asphalt driveway • A light-colored shingled roof What happens when a magnet breaks in half? (S8P5) • Each half is a new magnet, and both have a north pole and a south pole • One half has only a north pole, and the other half has only a south pole • Neither half is able to attract or repel • Neither half has a pole

  5. Mechanical energy is transformed into electrical energy by a(n) (S8P5) • Voltmeter • Transformer • Ammeter • Generator Radar technology uses radio waves that bounce off moving objects to tell how near or far away they are. This technology is similar to the natural ability of which animal? • A bat’s echolocation • A cat’s sharp hearing • A hawk’s keen eyesight • A wolf’s sensitive sense of smell
