Class: PHYL 205 Week: 2 Description: Graphs and Mathematical Relationships Virtual Lab Link: http://www.thephysicsaviary.com/Physics/Programs/Labs/GraphingOfMotionLab/ Instructions: Use the link below to run several simulations to determine the relationship between, distance, velocity and acceleration. Use the controls on the bottom left to start the virtual car and provide "gas" or "break". Observe the changes to the distance (on top) and the velocity as a function of time on the graph. Directions: 1. Run several simulations of increasing and decreasing acceleration 2. Show and provide screenshots of the general workings of the virtual laboratory 3. For each of the analysis questions, show a screenshot of the simulation and answer the questions Analysis questions:
1. What is the relationship between distance and velocity?
2. As velocity increase? Does the distance covered increase or decrease?
3. Can velocity be negative?
4. What is acceleration mean?
5. Can acceleration be negative?
6. Can velocity be positive and acceleration negative?
7. On the virtual simulation, where does one derive (determine) acceleration? HINT: show a screenshot and indicate where you can see the estimation of acceleration
8. How is acceleration and declaration related?
9. What is the maximum velocity that can be achieved in this simulation?
10. What is the maximum acceleration in this simulation? Estimate.
11. (A) For a car, what is more important, acceleration, velocity or distance traveled? Hint: Justify your answer! (B) Given acceleration, can you determine velocity? (C) Given ONLY distance traveled (example, 500m) can you determine velocity? (D) Given Velocity (example, 10m/s), can you determine acceleration?
