Class on Friday Jan. 15th

In class on Friday we talked about how to go about solving energy problems. Mr. Burk gave us some steps:

Guidelines For Energy Problems

1) Start by defining a system

2) Give symbols meaning (ex: instead of looking at a symbol like K and thinking of it as just K, think of it as change in kinetic energy)

3) Do everything symbolically

Also in class, we talked about power.

Also,

Power is measured in Joules per second or Watts. 1 Joule per second=1 Watt

Homwork is to finish 5C
