Graph 3. Distance (m) vs. average velocity^1/2 (m/s 2 ) based off figures in Table 1. Graph 4. Distance (m) vs. average velocity^3 (m/s 2 ) based off figures in Table 1. Acceleration of Gravity was calculated by using the proportion h/x=a/g V ^2=2 a x (from slope of V^2) graph a =0.1395/2 = g =8.72 m/s 2
Summary During this experiment, the speed of a glider was measured through a photo gate from multiple distances to examine the relationship between velocity and distance.The correct kinematic relationship found between distance and average velocity would be average velocity squared, which would show on a graph as a straight line.This explains the kinematic equation V 2 =V 0 2 +2a(X 1 -X 0 ) which shows the relationship between position and velocity. Another reason why average velocity squared was the correct relationship was because the R 2 value was 0.9998 which was the closest value to 1.Finally we found the gravitational acceleration to be 8.72 m/s 2 .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
