She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer?

If you have 10 minutes to spare by filling out a survey you'll be doing us a huge favor AND have a chance to win an awesome PBS Digital Studios shirt!
