SCH 501 PHYSICAL SCIENCE LAB Prof. Kenny L. Tapp Lab #3: Momentum PART I: DATA COLLECTION Watch the Momentum Lecture video to collect data for this Lab Exploration. 1. Mass oftheball: m= c. g = 0'0\"\"? k9 2. Length of track = cm = 3. Complete Table 5.1 using measured and calculated data. a. With the stopwatch, measure the time it takes for the ball to reach the end of the track (at its exit). Record the time value in seconds (3). b. Since the ball (metal bearing) is accelerating smoothly, the speed at the bottom of the ramp is twice the average speed. The average speed represents the entire length of the track over time (cm/s). i. Use the length of the track and the time to calculate average speed. ii. We need to calculate the final speed of the ball when it exited the track (reached the end of the track). Use this equation: Final speed = 2 x average speed c. Repeat these observations and calculations for books 2-4. 4. Use this space to show your work for converting units and/or calculating speeds. Page 2 of 3
