# Calculate the acceleration due to gravity

#### bnd_20191

1. Homework Statement
We need to calculate value for the acceleration due to gravity. We did a test were we dropped a ball from x height and recorded it.

Ball 1
0.65
0.82
0.95
0.79
0.81
0.9
0.91
0.85
0.76
Avg - 0.844

2. Homework Equations
Displacement formula

3. The Attempt at a Solution
I've attempted to change the formula and rewrite it, but I'm not quite sure.

Welcome to the PF. What do those numbers represent? What are the units? What is the expected error in your measurements (and what are the known sources of those errors)?

dropped a ball from x height and recorded it.
All the same height or different heights? What did you record? How did you calculate these numbers from your recordings?
You appear to have arrived at an estimate for g, but in your "attempt at solution" you refer to rewriting a formula. What formula and why are you rewriting it? Is this something you are asked to do?
What exactly are you seeking help on?
