Introduction

What is acceleration due to gravity?

• Mass independence
• Height dependence
• Show that g=9.8m/s^2 using G= 6.67 x10^-11 Formula: Fg=GM/r^2

There are companies out there that are interested in determining āgā accurately? What techniques do they use? (Make a research) These companies are researching g in the 3rd decimal point.

Experimental:

1. Equipment-list, picture specification
2. Procedure

Results and Discussion

PART A: Position vs time graph (plug the information of the graph in the excel and place the graph in the word document-comment on shape of graph and whether it is consistent with kinematic equation y-yo=Voyt+1/2ayt^2. In excel do 2nd order polynomial trend-line fit and find acceleration due to gravity from trend line equation). EACH TABLE NEEDS TO HAVE A GRAPH

Table 1

Table 2 acceleration(cm/s^2) from trend line eq. over %error (accept value 980cm/s^2)

PART B: Velocity over time

Table 3

Graph 2 on excel velocity over time. Comment on shape of graph and is it consistent with kinematic equation V=Vo+at ? Do a linear trend-line fit to determine acceleration from trend-line equation.

Table 4

Conclusion: Comment on the obtained acceleration values and explain why it might be different.
