From Motion diagrams to Position and Velocity Graphs
Name:
Group Members:
Date:
TA’s Name:
Apparatus: Aluminum track and a support, cart, plastic ruler, tape timer, and pencil
Objectives:
1) To be familiar with using motion diagrams.
2) To be familiar with displacement, time interval, instantaneous velocity, average velocity
and average acceleration.
3) To extract information from kinematic graphs.
Part A: Creating a Motion Diagram
The apparatus can be used to produce motion diagrams for a cart accelerating down an
incline plane (aluminum track). Your TA will demonstrate or assist you in using the tape
timer. Use the tape timer set at 10 Hz to produce a motion diagram for the cart moving
down the incline plane. In your tape, indicate the direction of motion using an arrow.
There must be at least 15 to 20 dots in your tape that can be used as data.
Part B: Measurement and Analysis of Motion Diagrams
1. Establish a coordinate system for the motion diagram and locate the position of each
dot. You may read the position to 1mm accuracy. Create a table with time and
position data in an Excel spread sheet. Your first data point should be a couple of
time intervals after the cart started to move. Your last data point should be before
anyone touched the cart to stop it.
2. Using your data, calculate the average velocity of the cart for the entire run. Don’t
forget about units. Show your calculation.
