1. Do you understand the conservation of mechanical energy as it changes from KE to PE (for example a flower pot falling from rest)?
2. If you have air-resistance (fluid drag) would the KE at the bottom just before impact be the same as the PE when the object was dropped from rest?
3. If you are holding a pencil in your hand does it have PE, KE or both?
4. What is PE dependent upon?
5. If a boulder and a pebble were on a cliff, which would have the greatest PE?
6. What is KE dependent on?

1. Discuss the similarities between the laws of Charles Coulomb's electromagnetic and Sir Isaac Newton's gravitational forces.
2. Discuss the similarities of electricity and flowing water. Consider voltage/pressure, conductor/pipe size and amperes/volume.
3. Describe charge flow direction during battery discharging
4. Describe charge flow direction during capacitor charging and discharging and investigate capacitor usage in modern society.
5. What is the source of charge in a complete circuit (battery, conductor, switch, load)?
6. What does short circuit mean?

1. What happens to the image when the object is placed at the focal point of the lens?
2. When would you place an object between the lens and the focal point?
3. What does the focal length of the lens depend on?
4. On a wave diagram where would you label the crest?
5. On a wave diagram where would you measure the amplitude?
6. On a wave diagram where would you measure the wavelength?
7. If I measured the time it took for one wave to pass a point would this be the period or the frequency of the wave?
