Thanks for the responses thus far - it's been a big help. Below are concepts I've pulled out of the above replies. If you can think of any more please add them. Now I'd like to see if I can have you rank these concepts in order of their relatedness to the scenario. In other words, if...

"Impact energy" is another good term - thanks! Don't know what to say about cyclists "playing" somewhere else. The first automobile accident ever recorded in the US was a car vs. bicycle, and there has been conflict ever since. Just please think about the variety of benefits cycling vs...

Ah ha! Momentum! That's the kind of thing I'm looking for. Can you identify some of the other physics concepts that come into play and how?

This is for an educational research project in bike safety education. Currently, riding with traffic is seen by bike safety educators as a high-priority safety practice. However, it is generally taught as a rule to follow without providing an underlying rationale. I'm going to compare the...

What are the formal principles of math and physics that describe this scenario? Most local laws require bicyclists to ride with (i.e. in the same direction as) traffic. The rationale behind this is that as a car and a bike are traveling in the same direction the car has more time to react to...
