Uniform Motion
Date: _______________________________
Period: ______________________________
Question:
What can measuring the speed of an object tell us about its motion?
Experimental Design:
In this lab the speed of toy cars will be determined using a ticker tape timer. Distance is from the time points on the
ticker tape. The data is recorded and plotted on a graph to observe the type of motion..
The variables are:

Materials:
- Ticker tape
- Ticker tape timer
-
Toy cars
-
Meter stick
Observations:
Note:In order to accurately record the data the following steps must be taken. The ticker tape timer must be set to
10Hz; this corresponds to every 0.1 seconds
1. Label each one of the points t0, t1, t2, ... etc. as shown above until you have reached the end of your ticker tape
2. Measure the distance from t0 to each one of the points as shown. You must start your measurement from t 0.
3. Record your measurements in the data table below. Be sure to use the proper time interval

Analysis:
Using graphical analysis, determine the average speed of a toy car.
- A graph representing the distance as a function of time of each of the toy cars. Plot your data on the grid below.
Be sure to follow the “graphing guidelines” handout when creating your graph. Be sure to label each axis,
provide a title, use and accurate scale, plot your points clearly and draw a line of best fit.
- Determine the slope of the line of best fit and algebraically relate your value to the appropriate physics concept.
Slope Calculations and Units
Conclusion:
Provide a brief summary of your results. Ensure to explain how the “slope of the line of best fit” is connected to the type
of motion being observed. If there were any sources of error encountered in the lab, please note how it affected the
data.

This is the rubric that will be used to mark your uniform motion lab. Please read through it carefully and ask questions as you need. It is encouraged that you
complete your lab early in order to improve on the quality of work by having yourself, your peers, and the teacher proof read your lab prior to being evaluated.
