Physics and Astronomy Labs/Uniform acceleration tapping basketball with spitwads
First, students divide roles amongst themselves. One for timing, another for tapping the basketball, then other students number themselves for shooting spit balls. Next, mark five consecutive tiles with markers. Tiles must be a foot in length. Then, at the start of the first tile the designated student will begin repeatedly beating the basketball in a straight line. As the student beats the ball, to maintain a constant acceleration, the timer will call out every second. The spit ballers will shoot their spit balls at the basketball when their number is called. After five tiles the distance of the spit balls at that second will be recorded.
