- Explain how to calculate the slope of a line.
- The slope of a position vs. time graph is equal to the object’s ____.
- Sam rolls down his driveway on a skateboard while Beth keeps track of his position every second for 15 seconds. When they make a graph of the data, the position vs. time graph is a curve that gets steeper as time increases. What does this tell you about Sam’s speed?
- Sketch the speed vs. time graph for an object moving at a constant speed of 3 m/sec.
- You drop a ball from the edge of a cliff. It lands 4 seconds later.
- What is the ball’s average speed during the first second it is in free fall?
- What is the ball’s average speed for the whole 4 second?
- Draw the position vs. time graph for a person walking at a constant speed of 1 m/sec for 10 seconds. On the same axes, draw the graph for a person running at a constant speed of 4 m/sec.
- Calculate speed from the position vs. time graph to the right. Show your work.
- Draw the position vs. time graph for an object that is not moving.
- Why is the position vs. time graph for an object in free fall a curve?
