For this section you will be required to analyze a set of data, plot a graph, perform calculations and analyze the results. To complete this section properly, you may need to read the Physics 11 Reading 2 document again.

An experiment was performed where a student rode her bike at constant speed along a flat and straight path. At different intervals, her distance in metres (m) and time in seconds (s) were measured and recorded in the table below.

d(m) / t(s)
0 / 0
160 / 8.0
250 / 12.5
400 / 20.0
590 / 29.5

PART E: PHYSICS INTRODUCTORY LAB – The Ticker Tape Analysis

A common way of analyzing the motion of objects in physics labs is to perform a ticker tape analysis. A long tape is attached to a moving object and threaded through a device that places a tick upon the tape at regular intervals of time – say every 0.1 second. As the object moves, it drags the tape through the “ticker,” thus leaving a trail of dots. The trail of dots provides a history of the object’s motion and is therefore a representation of the object’s motion. Ticker tape diagrams are sometimes referred to as oil drop diagrams. Imagine a car with a leaky engine that drips oil at a regular rate. As the car travels through town, it would leave a trace of oil on the street.

The distance between dots on a ticker tape represents the object’s position change during that time interval:

  • A large distance between dots indicates that the object was moving fast during that time interval.
  • A small distance between dots means the object was moving slowly during that time interval.

The analysis of a ticker tape diagram will also reveal if the object is moving with a constant velocity or with a changing velocity (accelerating).

  • A changing distance between dots indicates a changing velocity and therefore an acceleration.
  • A constant distance between dots represents a constant velocity and therefore no acceleration.

Purpose: Analyze data from a ticker tape to determine aspects of an object’s motion.

Materials:ticker tape (provided- see diagram below)

metric ruler

Time interval represented by each successive dot is 0.1 s.

Procedure:

  1. Print off this page.
  1. Using a ruler and beginning at the first dot (t=0), measure in centimeters the distance on the ticker tape of the first time interval (between the centers of dots t=0s and t=0.1s). Record this distance as the displacement of the object during 0.1s in the data table provided (to the nearest tenth of a centimeter).
  1. Continue measuring the displacement of the object for each successive interval (t=0.1s  t=0.2s; t=0.2s  t=0.3s, etc.) and record each value in the table.
  1. Calculate the average velocity during each time interval. Remember that the time interval for each measurement is 0.1s and the displacement is the distance traveled during that time.
  1. The total displacement of the object at the end of any given interval is the sum of the displacements during each preceding interval plus the current measurement (i.e., total displacement from t=0). Calculate the total displacement of the vehicle for each interval and record the values in the table below.
  1. Calculate acceleration of the object during each time interval. To do so:

a)Find the change in velocity; it is determined by subtracting the object’s velocity during the previous time interval by the object’s current velocity, or v2 – v1.

b)Remember that acceleration is the change in velocity during a time interval. In this case, each time interval is 0.1s, so the acceleration is:

Observations and Data: (8 marks)

(s) / Displacement (cm) / Average Velocity (cm/s) / Total Displacement (cm) / Acceleration (cm/s2)
0.1 / n/a

0.3
0.4
0.5
0.6
0.7
0.8
0.9
1.0

Analysis and Conclusions:

  1. Using the data, create a position-time graph using total displacement data from your table. Be sure that the graph has a title and that all axes are properly labeled. If you are not sure how to do this, refer to the following lesson: Basic Requirements of All Graphs. If you’re drawing the graph on the computer, use InsertPictureChart; otherwise, plot on a separate piece of graph paper. (4 marks)

Insert Graph Here

  1. Write an explanation for what this graph shows. Be sure to point out any changes in the slope of the line and what these changes tell us about the changes in the vehicle’s motion. (3 marks)
  1. Using the data and the same methods as in #1, create a velocity-time graph. Use the same size scale on the x-axis for time intervals as you did for your last graph. (4 marks)

Insert Graph Here

  1. Write an explanation for what the graph shows. Point out any location(s) on the graph that shows constant velocity and changing velocity. (3 marks)
  1. Calculate the object’s average velocity for the entire trip. (2 marks)

How does it compare to the velocities during each interval? (1 mark)

  1. The area under your velocity-time graph represents the displacement of the vehicle.

a)Calculate the area under the line for 0-0.5seconds. Show all work. (2 marks)

b)How does this compare to the total displacement found in your data for 0.5s. (1 mark)

  1. List a source of error and explain how it could have affected the results of this lab. (2 marks)
