Using the wrong charge when working out the electric potential difference for an alpha particle in moving from it's starting position to when it stops a short distance from a gold nucleus. For some reason, you have to use the charge of the gold nucleus instead of the charge of the alpha particle??
•
Not knowing that the work done in bringing the alpha particle to a stop equals the loss in kinetic energy. I equated the kinetic energy to the electric potential difference instead..
•
Getting the 'm' prefix mixed up with the 'M' prefix. Grrr.
•
Not remembering the definition for a force field. I now know that it is a region in which a body experiences a non-contact force.
•
I have now almost finished making notes on the AS topics. I just need to go over wave-particle duality from the Quantum topic.
•
I have started answering questions on each sub-topic from both of my textbooks (Doing AS Electricity at the moment).
•
I have made some better notes on Magnetic Fields because the ones I made in class a few weeks ago make no sense.
•
Today I've nearly completed the Magnetic Fields homework booklet that my teacher gave us as a Christmas present. I just have two questions left- one which I don't understand and one which I need to draw a graph for but I can't be bothered to look for a pencil.
