Free Fall Lab
Problem Statement:
In the following lab report, the following questions will be answered that have to do with the average acceleration due to the gravity on an object in free fall : 1. List the experimental acceleration due to gravity that you measured at each distance 2. Which value do you believe is the most accurate? Why? 3. What factors do you believe contribute to experimental error in this measurement?
4. What could be done to improve the quality of the result? How could change the experiment?
Background Knowledge:
In reference to Sir Isaac Newton, we know that in free fall an object moves towards the surface of the Earth with a uniform accelerated motion due to gravity. With that being the case we also know that the further that an object falls, the faster the speed will be. …show more content…
Experiment:
First I put a piece of tape on the wall and measured out and marked at 0ft, 2ft, 4ft, and 8ft on the tape. With the 0ft mark being farthest from the floor. I then had my helper stand with the golf ball at the 0ft mark and she released the ball as I timed when the ball passed the particular line I was measuring for. I repeated this for each line 5 times and recorded each time the ball passed each line.
Data Table:
The data table will represent if the change in distance will change the amount of acceleration
Independent Variable: Distance
Dependent Variable: Acceleration
The acceleration was calculated by the formula: 2(distance)ft/Average^2sec
