Lab Report
Research Question: To determine the speed of a pulse in a thin metallic spring.
Variables:
- Dependent: Length of spring
- Independent: Period of pulse
- Control: How big the pulse is
Equipment:
- Thin metallic spring
- Chairs(x2)
- Stopwatch
Methodology Setup:
Methodology:
- Two chairs were aligned as bases, one opposite of the other with a distance of 6,49 m and a spring was attached at the end of each chair.
- One person operated the stop watch, while the other created the pulses. A third person wrote down the results shown in the stopwatch.
- The stopwatch was simultaneously operated so it would start counting when the pulse was created and stop counting when the pulse returned to the base that it started.
- When the stopwatch stopped counting, the results were observed and written down.
- The total results where 45.
