Question
Bonus Problem: Does the line pass through the origin? Is it shifted to the left of the origin, or to the right? If it is shifted to the right, this is because of friction in the pulleys. If there is friction in the pulleys, the tension in the string on the mass #1 side will be larger than the tension in the mass #2 side, by the value of the frictional force. Can you use this information to prove that the frictional force through out the lab would be equal to the x-axis intercept of the line times g? M, = x axis intercept If you can prove this in the theory section of your report, you may earn a bonus to your grade. If you have no idea how to do this, don't worry, this is only a bonus problem!Explanation / Answer
the line is not passing throug the origin and shifted towards left to the origin.
and hence according to the information given in the question, shift towards left to the origin is not because of friction in pulleys.and hence there is no froction force.
non existence of friction force can also be seen from graph also, line dose not cut any intercept on x-axis and so intercept on x-axis is 0 and hence friction force.
