The equipments we used in the experiment consists of elastic spring, steel ball bearing, spring launcher, platform, string, measurement ruler and also nail.
As our group carried out the experiment, the procedure are as following:
1. First, the spring launcher is set on the platform of 1.3m height with the ball bearing loaded. The spring is attached to the back of the launcher and fixed. The spring inside the launcher is then pulled backward to a certain displacement x1 and held by the nail on the launcher before launched. The measurement ruler is also set on the landing platform to take measurement.
2. The steel ball bearing is launched by pulling out the nail on the launcher and the distance travelled by the ball bearing is recorded by the observer. The experiment is repeated for the same displacement for at least 3 times to get accurate result.
3. The above steps are repeated for the different displacements x2 , x3 and x4. The data taken are recorded and tabulated in the table for calculations purpose.
