ill type down the questions here:
1. multiply your chosen maximum or minimum force( i had a downward maximum force of 9.220 N so use that) by the calibration correction(actual force/measured force). the result is the actual maximum or minimum force for that signal.
2.calculate the actual net force
3. using the actual net force from step two, calculate the acceleration.
b.
4.using newton's second law, calculate the expected value of the spring force when the spring scale and weight are in free fall(for this acceleration, it will be useful to define up as positive, down as negative, and therefore acceleration as =-g.
c
5.based on your measured falling distance and time, calculate the acceleration of the system
6. based on newton's second law, calculate what the acceleration would be if the system were frictionless. hints: the mass is the sum of the masses on both sides, whereas the net force is the difference between the weights of the two sides.
7. choose which of the following best describes your results.
a) the measured acceleration(5) is greater than the calculated acceleration, which is suprising since we should expect friction to reduce the acceleration.
b)the measured acceleration is greater than the calculated acceleration, which is to be expected since we should expect friction to increase the acceleration.
c)the measured accceleration is less than the calculated acceleration which is suprising since we should expect friction to increase the acceleration.
d)the measured acceleration is less than the calculated acceleration which is expected since we should expect fricition to increase the acceleration.
