In this lab, we want to use our knowledge of projectile motion, to predict the impact point of the ball on the board.
First, we set up the apparatus as shown in the picture below.
Next, we roll a ball down the ramp and we mark where we think the ball land on the ground with tape. After that, we put a piece of paper on top of the tape mark. after that we put a carbon paper on the paper. Then we let the ball roll down the ramp and the impact would cause the carbon paper to make a mark on the paper underneath. We rolled the ball another 4 times, so a total of five marks on the paper and took the average of those distances from the table. Also we measured the height of the table. With all that information, we can derive a formula and calculate our uncertainty. Look at the picture below.
After that we use these two formulas to help us derive an equation to help us calculate the how far down the board it will hit and its uncertainty.
In this lab, I learned that with my knowledge of projectile motion and propagated uncertainty, I can predict where a ball will have an impact on an incline board.9
