![]() These trial-runs should help you take your actual data more efficiently and effectively.įor your lab report, take two sets of data: a constant velocity towards the ranger and a constant velocity away from the ranger. ![]() ![]() Push a cart forwards and backwards to see what this looks like on the graph. Make a graph of a slow cart moving forwards and a fast cart moving backwards to see what the difference looks like on a graph. You should be able to indicate how you would see each effect in the graphs of the motion.īefore taking data for the lab, develop your familiarity with the equipment by playing with making velocity versus time measurements. If the track has friction with no tilt then describe the motion in each direction using the phrases “speeding up” or “slowing down”. If the track is tilted with no friction then describe the motion in each direction using the phrases “speeding up” or “slowing down”. (This is explained in Appendix C.) Checkpoint 3.1. Capstone, via the sonic ranger, can measure the position and velocity of the cart as a function of time. (You might need to use the “sail” for the sensor to see the cart.) ![]() Place the sensor about 20 cm from the end of the track, because this is the minimum distance detected by the sensor. 4 Newton's \(2^\) Place a steel ball on the track and adjust the leveling screw at one end of the track to see if the ball rolls one way or the other. ![]()
