LECTURE 26
questions before lecture
think about these
- What causes gravity?
- In the Principle of Equivalence from last lecture, what was gravity equivalent to?
- How wide a swath does a total solar eclipse cut?
- Define refraction (yes, in optics).
- Do you know what a scalar is? A vector? Can you give an example of each?
- Here's a hard one. In an accelerating system, would you get the same feeling as being closer to a mass, at the front or rear of the system?
