1. Check that the air track is level (horizontal). It should take the glider at least 10 seconds to move across the track, no matter at which end it is placed. If it is not sufficiently level check with your instructor.

2. Measure:

a) The distance D the glider moves in going from one end of the track to the other.

b) The distance L between the base supports of the air track.

3. Place one spacer under the single track support. With the air on, place the glider at the upper end with about one millimeter gap between the glider and the stationary spring. Take a few practice timings to get used to starting the clock at the time the glider is released, and stopping the clock when it hits the spring at the lower end. Be careful when reading the clock. The two dials have different divisions. When you are used to the process of release and timing, then proceed.

4. Set up a table with the headings shown below:   

Be sure to indicate the units used. For each value of n, from 1 to 4, measure the time twice. If they differ by more than 5%, then take another pair of times. Continue until two successive times are within 5%.

5. With four blocks in place, n = 4, take a total of six times. We will use this information to determine the variability in our time measurements.

Part B: Determining the dissipated energy

1. With two spacers, measure the rebound distance D’. Use the average of two successive measurements that are within 5% of each other.

2. Evaluate the fraction of the original kinetic energy that is lost in the collision.

Journal lab 3 - Kinematics: Describing A One-Dimensional Motion

Experiment of kinematics in describing a one-dimensional motion is conducted to investigate the velocity of air glider both in rebound and not rebound which is in three different forces applied; fastest, fast and slow. Before began the experiment, the air track should be adjusted to be level and a glider should not try to move either direction. The time is taken through the reading of stopwatch as the glider passed each interval of 2 seconds for 10 seconds timing. The force applied by a person only so that the individual know better to push the glider at slow, fast and fastest speed. 

I found out some error while conducting the experiment. First, my group did not level the air track properly and thus, we need to start back the experiment. Second, we need to measure the unit measurement on the air glider and avoiding parallax error and the unit should be converted into meter since we want to determine the velocity of the glider.

This experiment is quite easy but a little bit tricky at first since I did not know how to 

level the air track and yet, it is a good knowledge to explore about physics.
