Name: Cliff Hults Partner(s): Lindsay Ross, Kevyn States Date of Lab: 10/17 Title: Acceleration of Gravity Purpose: To measure the acceleration of gravity, We will compare this result with the commonly accepted value of 9.8 m/s2 Materials: Multiple Balls, Stop watch, Bleachers, String, Meter stick Procedure: 1. Collect Information 2. Measure the height from the top of the bleachers to the ground. 3. Drop Metal ball 1 from the top 4. Stop watch once ball hits the ground 5. Record Data 6. Repeat process for all balls Data Table(s): Height of Bleachers: 106inches = 2.69meters X= gt 2 /2 G=2x/t 2 Test # Ball Type Time 1 Metal 1
