Physics

This is a finding on the topic that we are doing on, on which other people have tried out.

The person tested on vegetable oil, baby oil, Vaseline and Softsoap. He built a ramp and separated the substances into four different containers, in which a disposable paintbrush was placed. He had a stopwatch accurate to the hundredth of a second and distilled white vinegar to clean the substance off the ramp after the testing. He then slid a metal block down the ramp and recorded the timing.

These are the average times it took the block to read the end of the ramp with each lubricant: Softsoap = 0.63 sec. baby oil = 0.88 sec. vegetable oil = 1.01 sec. Vaseline = 1.22 sec.

The guy learned that because a substance is dense it does not mean that it cannot lubricate. One problem he had during the experiment was the cleaning of the ramp. He used a soap to clean the ramp initially, then realised that it was unfair as one of the substances was a type of soap too. So, he changed to using distilled white vinegar

The steps he took were as follows:
1)Statement of purpose and hypothesis
2)Methodology
3)Analysis of data
4)Summary and conclusion
5) Application
