Expands on the interpretation of the elevator data discussed in class by analyzing the downward part of the elevator trip and leads to a definition of true weight and apparent weight. The correlation is made between these terms and an elevator rider "feeling" heavier or lighter.
You should be able to answer the following after having viewed this tutorial:
1. How do acceleration and velocity directions compare for an elevator moving downward and a) speeding up and b) slowing down?
2. How do the direction of the net force and the acceleration compare?
3. During an elevator ride, which force (gravitational or normal) changes and which remains constant?
4. State the difference between true weight and apparent weight.
