#### Transcript of Gravity

Introduction
Gravity
Our objective was to verify the gravitational constant.
Objective
Results/Data
Hypothesis
taught how to measure gravitational constant
human error
average-0.78 0.861
relativity
Discussion
find a place to drop your objects from
measure the height from the ground and record it
drop each object from that spot 10x and record the time it takes to hit the ground
Procedure
Issac Newton- Scientist who first discovered gravity, still very little known.
Einstein- built on Issac's words and fully explained gravity.
Theory of relativity- Einstein's explanation of relativity.

The purpose of this lab was to measure the gravitational constant.
In the beginning of this experiment we hypothesized that any any object dropped from the same height would land at the same time.
After coming to an end of our experiment we found out many human errors which affected our hypothesis. Tennis ball: 9.7 % of total error and for the golf ball we had a total of 33.7% error.
