Section 7.2 Review En
1. Martha wakes up at 5:30 a. m. and cats a bowl of corn flakes. It's a nice
day, so she decides to ride her bicycle to work, which is uphill from her
house. It is still dark outside. Martha's bike has a small electric
generator that runs from the front wheel. She ſlips on the generator so
that her headlight comes on when she starts to pedal. She then rides her
bike to work. Draw a diagram that shows the energy transformations
that occur in this situation,
