Hi folks,
Today we spent quite a bit of time on a lab in order to try to better understand acceleration. We also used a computer simulation to get the hang of graphing velocity, distance and acceleration.
Homework for this week is:
Finish off the data table for all spheres and slopes. (Including the data table for the last trial you did with the time for each foot of the ramp.)
Make the following graphs:
1. Velocity vs. Time graph for the last trial you did where you measured times for each foot..
2. Acceleration vs. Time graph for the same trial. (Please use graph paper for both of these graphs.)
Using those graphs answer the following questions.
1. At what point on the ramp did the ball have the highest speed?
2. What would you estimate the speed of the ball to be if the ramp was long enough to allow the ball to travel for one more second.
3. What was the average speed of the ball for the entire ramp?
4. When was acceleration greatest or was it constant?
5. If it wasn't constant….why not?
6. What was the average acceleration of the ball for the entire ramp?
7. What would the acceleration be if the ramp was long enough to allow the ball to travel for one more second. (Estimate this using your graph.)
