Data table: Title, Labels, Units (Make sure to use Sin Ɵ values with 4 digits after decimal point)
2) MS Excel (much easier!!) or other spreadsheet Graph:
- Title, Labeled axes including units
- Scatter plot: Acceleration vs Sin Ɵ from the experiment, no connecting line
- Trendline (linear), display an equation, R^2 coefficient, set y-intercept at 0.
- Using the equation, calculate the acceleration value for sin Ɵ = 1. What could it be? - Write some
comments
Equation : y=9.2049x
(insert when sin theta is equal to 1)
Y= 9.2049(1)
Y= 9.2049 m/s^2 average acceleration
Possible Calculation errors
