Question

A student is working on an Atwood's machine experiment. The student recorded and plotted acceleration [m/s/s] vs mass difference [in grams, g, not kg]. The student does the fitting and gets a = 0.05 Am -0.1.What are the missing units on the y-intercept in terms of meters, seconds, and grams? m^ *s^ *g^ A student is working on an Atwood's machine experiment.

Explanation / Answer

3)
y intercept should have same unit as acceleration a

so unit of y intercept:
m^1 * s^-2 * g^0

4)
0.05* delta m should have same unit as acceleration a
unit of 0.05* g = m/s^2
unit of 0.05 = m/(s^2*g)

so unit of slope:
m^1 * s^-2 * g^-1
