Question

Explain whether or not you would trust any conclusions obtained from this data. When formulating your answer, consider whether or not the effects of friction could account for the results these students obtained. What could the students have done wrong

Answer 1

Please find the complete question in the attached file.

Step-by-step explanation:

This graph as seen in the question must not be trusted. The reason for this is the plotted line of genesis desnt.

F=Ma

When F is in the axis (x,y) and mass of the system of the arc must be plotted F = 0 if a = 0 is considered as the perfectly friction-less ground.

This might be the case, as noted correctly, with such a surface tension opposite our twisting motion, in there is a coercing vertex even when the velocity of the body is zero, that is an example of friction force where the beginning pressure is working against frictional without moving or speeding up the body.

Concerning whatever the students got right, the complete experiment I knew is only evaluated correctly, but some of the suggestions clean the surface before exp, place the oil surface film and doing the experiment on an emptied ship; minimize that friction component.
