- If you have a distance – time graph of the speed of an automobile and it is NOT a straight line, what does that mean?
- On a distance – time graph for a vehicle moving at a constant speed, describe the slope of the line if the car is moving …. a) very fast, b) parked and not moving, c) moving slowly
- Imagine that you could ride a baseball that is hit hard enough for a home run. Using the concept of frame of reference, describe what is happening from these perspectives: a) batter, b) you sitting on top of the baseball, c) outfielder trying to catch the hit.

- Look at the Distance Vs. Time graph on the bottom left-hand corner of page 370. Visually compare the red line with the blue line and green line. Calculate the slope of the red line.
