Here is a Video of me & my partner taking on the experiment…
In this lab we explored Newton’s 2nd
Law.
1. Newton’s 2nd Law i.e
2. The law of conservation
of energy
3.Velocity and acceleration
4. Power
In the experiment, we altered the amount of weight used on the pulley, and using the Lab View computer program we were able to adjust the power levels to lift the weights…We discovered that less weight made the pulley go faster, as did higher power levels when the weight was unchanging. Likewise, heavier weights and lower power levels slowed it down. After collecting the data, it was transferred to a
Microsoft Excel template, shown in the image below.We then arranged the first four attempts that had the same amount of weight and
different power levels, and the last four have different weights but the same power level. After this, we put it all into several graphs.
