Writing your Report
Once you have collected your data and analysed it, you can begin to compile your report. The outline and checklist
for each of these sections is provided.

Outline of Section
An accurate, concise description of the
project, which provides the reader with an idea
of what the investigation is about
A single page listing the contents of the report,
and what page each section is on. A Table of
Diagrams may also be relevant.
A theoretical and descriptive introduction to
the project. It should outline the theoretical
background of the project
An accurate description of materials used and
experimental procedures, allowing the
investigation to be repeated
A full description of all data, with use of tables
and figures to summarise and present findings
The place to describe the relevance of your
results and any limitations in your approach
i.e. Providing the reader with an interpretation
of both qualitative and quantitative data
A summary of your analysis. What are the
key points that can be drawn from the results
and analysis
An alphabetical list of all sources used during
the project.

PROJECTILE MOTION – VIDEO ANALYSIS WITH “LOGGER PRO”
Aim:
To examine the horizontal and vertical components of projectile motion,
To develop familiarisation with video analysis, and
To increase awareness of using gradients from graphs.
Equipment:
Digital Video camera (or a digital still that can take digital footage in AVI format)
Photographic tripod
metre rulers (2)
a ball (tennis ball or bigger)
(Note: the ball must not be light enough for the wind to have a significant effect on it)
Instructions:
1. Clear an area where the ball will be thrown – you will need about 5 to 8 metres.
2. Set up the camera at least 10m away (side on to where the ball will be thrown).
3. Set up the two rulers end to end directly under where the ball will be travelling.
4. Adjust the zoom on the camera until you have the whole throwing area in field of view –
including the two metre rulers.
5. Record two throws of the ball – one throw should be a slow loopy throw, the other should be
a bit flatter.
6. Download (“capture”) the video footage to the computers and use Logger Pro to analyse the
videos as shown in class. You will need for your results:
a. a graph for each throw with horizontal and vertical position versus time,
b. a graph for each throw with horizontal and vertical velocity versus time. On each
graph you should show the line of best fit as described below…
c. the horizontal and vertical acceleration for each throw is determined by the gradient
of the line of best fit:
i. Select the points on the graph you want the computer to use for the line of
best fit.
ii. Select Analyse/Linear Fit.
iii. Right click in the data box for the linear fit. Choose “Linear Fit Options…”
and check “Slope” under “Standard Deviations”.
Questions/Analysis:
Q1. What do you notice about the vertical acceleration (or “y” acceleration) for each throw?
Q2. What do you notice about the horizontal (or “x” acceleration for each throw?
Q3. How does this acceleration compare with the acceleration due to gravity on an object falling
straight down?
Q4. Calculate the error in the acceleration for each throw
% error 
accepted value  experiment result
accepted value
Research:
Q5. The initial velocity of the ball is found from the vector addition of the horizontal (or “x”)
velocity and the vertical (or “y”) velocity. Find out how to do a vector addition and
determine the initial velocity of the ball for both the throws.
Q6. There is a fairly simple formula to predict the maximum height of a projectile from the initial
velocity of the projectile and its angle of elevation. Find this rule and use it to predict the
maximum height from the velocities found in part a.
