I discussed the differences between distance traveled and displacement as well as the differences between speed and velocity.
1. A man walks 5 meters east.
What distance did he travel? What is his displacement?
2. A man walks 5 meters east the turns left and walks 5 meters north.
What distance did he travel? What is his displaceent? (How far is he from where he started)
3. A man walks in a circle with a 5 meters radius.
What distance did he travel? What is his displacement?
4. A man follows the path indicated in the diagram, starting at point A. The first two legs of this trip are 500m each.
Calculate the total distance traveled after each leg.
A to B
A to C
A to A
Calculate the displacement relative to A after each leg.
A to B
A to C
A to A
5. A man gets in his car and drives for 10 minutes covering a distance of 15 miles. He stops for a Snapple break for 5 minutes and then drives for 25 miles at a rate of 40 mph. Assume the man is traveling north while he is driving.
Draw a distance-time graph describing the journey.
How far did the man travel?
How long was his trip? (time)
What was his instantaneous velocity during each leg of his trip?
What was his average velocity for the trip?
6. In each of the following graphs discuss the motion of the object(s) relative to where the object began.
7. Draw two lines: one representing the average velocity, the other representing the instantaneous velocity at the point marked of the graph.
