Check the x and h values every time it is critical that they stay constant!). Repeat previous steps for a total of 5 different inclinations. ALYSIS Using trigonometry and your values of d and h, calculate the sin 0. Average the three trials for each inclination and complete the analysis table below.

DATA COLLECTION 1. Set up the air track with one cart with a "flag" on top of it. Place one photogate near the end of the track. 2. Measure what is called the effective length" (Left) of the flag on top of your cart. You do that by measuring the position of the flag when it starts to bock the photogate, and the position of the should not be on at this time.) Nag when it has passed through and just stopped blocking the photogate. (Note: the track 3. Adjust the air track so that it forms an inclined surface with the tabletop. Determine a location on your track to be your starting point, you will be consistently placing the cart so that the center of the flag on top of it is always placed at the starting point. Measure the distance x from the starting point to the center of the photogate. 4. Turn the air track on. Once the track is operating at full strength, release the cart. Record the time At during which the photogate is blocked, and convert that reading to seconds. 5. The average velocity of the cart as it is blocking the photogate is equal to Lew/AL. Use this value of v, and the measured value of x, to determine the acceleration of the cart over that distance. 6. Record acalculated in the data table below. This is your first trial measuring the acceleration. 7. Measure the distance d between the two vertical supports of the air track, and the height h by which one of these supports was elevated. You will use these values to determine the sin of the incline (not o, but sin 0; you do not need the value of in this lab, only the sine function!!!!! Do not calculate O first, to obtain sino later this introduces important rounding errors. Get sin o directly from d and h). Important: the most common issue in this experiment is the incorrect measurements of x and II, which are absolutely necessary to get sin , otherwise this experiment is useless. Notice that d and I must be measured in respect to the same position. Have all members of the group measure d and h every time, and THINK about how you are doing this.
