Investigating Projectile Motion
Colin, Harrison, Lily
Given the materials needed, create a lab where you demonstrate your understanding of projectile motion. Your final product is an addition to your Weebly as a lab report.
You should have the following:
Before conducting your experiment:
· Objective What is the purpose of the lab? What are you trying to prove/show? Or… What is the question you want to be answered as a result of the lab?
The objective of this lab is to find the X Velocity, Y Velocity, Y Distance, Horizontal Distance, and the Time. Also to discover how precise the equations are when solving for distance compared to the actual distance covered.
· Material· Procedure – Step by step, numbered/bullet points, on how you are conducting your experiment.
Photogate, Ramp, Labquest, Rulers, Marble,
We will construct the Ramp, and set up the photogate, and perform the experiment to get the data. Then we will upload our data to our individual Weeblys.
During your experiment:
· Data
· Data table- include several trials
· Picture of your lab set up

After your experiment:
· Analysis - Discussion of your results in detail – this should be more than 1-2 sentences.
What did you exactly do? What did your results show?
We first timed and found the velocity for four trials which we used to find the distance for which the marble should end up. We then did the experiment without using the photogate and recorded the distances which it actually landed. We figured out that the distance we predicted through the equation was about 20cm further than where it actually landed.
· Calculations for each trial
1st Trial’s Calculation for vertical distance traveled: 0.09995 meters
2nd Trial’s Calculation for vertical distance traveled: 0.09992 meters
3rd Trial’s Calculation for vertical distance traveled: 0.09991 meters
4th Trial’s Calculation for vertical distance traveled: 0.09986 meters
· Conclusion - Discuss why you did this lab. Anyone reading just this part of the lab should understand what/why you did without looking at any other part of your lab report. Discuss whether your hypothesis was proven correct. Discuss any inconsistencies or errors that you can think of.
We did this lab to explore how equations such as dy=.5gt squared can predict one of the variables like Dx without actually doing the experiment. The equations were not very accurate as to where the marble landed. They were as off as 20 centimeters off the actual landing point. We had about two errors in our experiment. The marble was not dropped at the exact same point each time. The friction from the ball rolling also made the distance a little off.
