Need help simplifying units of slope for an angular acceleration vs torque graph

  • #1

Main Question or Discussion Point

In a lab we conducted in class we graphed angular acceleration vs torque, and found a positive linear correlation-easy enough. However I am getting rather stuck in simplifying the units of slope in terms of Kg, m, and s... I am fairly sure this will give me that angular acceleration equals torque times inertia but I have trouble with simplifying the slope AND with even getting torque and angular acceleration simplified to kg m and s. I would really appreciate some help! thanks!!

sorry pal, inertia is not a quantity, but inertial mass is.

[tex]τ=Iα[/tex]

[tex]I=mr^{2}[/tex]

[tex]α=\frac{d^{2}θ}{dt^{2}}[/tex]

And the units of α is s^-2. m stands for mass.
