Ball+Lab+Report

Part 1 & 2

Materials:  -  2 meter sticks  -  2 metal balls (small and medium)  -  1 stop watch  -  1 physics textbook  -  tape  -  tape measure

Procedure: Create a ramp using 2 meter sticks, take, and your textbook Go to the hallway Roll the ball (medium) down the ramp and time the trip from start to finish (x5) Make a table for your data calculate average velocity for each roll Calculate overall average for the balls Repeat with small ball

Raw and Processed Data: Medium Ball
 * Trials || Time (seconds) || Distance (meters) || Average Velocity(m/s) ||
 * 1 || 3.89 || 3.04 || 0.781 ||
 * 2 || 4.10 || 3.10 || 0.756 ||
 * 3 || 4.28 || 3.15 || 0.736 ||
 * 4 || 4.21 || 3.07 || 0.729 ||
 * 5 || 3.88 || 3.12 || 0.804 ||
 * Average || 4.07 || 3.10 || 0.761 ||

Small Ball
 * Trials || Time (seconds) || Distance (meters) || Average Velocity(m/s) ||
 * 1 || 3.87 || 2.96 || 0.765 ||
 * 2 || 4.16 || 2.90 || 0.697 ||
 * 3 || 4.19 || 2.94 || 0.702 ||
 * 4 || 3.85 || 3.00 || 0.779 ||
 * 5 || 4.19 || 2.94 || 0.702 ||
 * Average || 4.05 || 2.95 || 0.729 ||

In this lab we found that the medium ball had a higher average velocity. It traveled further distances in either around the same or in lesser time. Part 3

 * 10 ||  2.56  ||  0.391  ||  -  ||
 * Average || 2.61  ||  0.383  ||  0.147  ||

Conclusion: We found that the medium ball has a higher average velocity and average acceleration than the smaller ball.
