## Main Question or Discussion Point

In rotational motion ,

the units for

are N [itex]\cdot[/itex] m

and for

[itex]W = \int_{\theta1}^{\theta2} \tau \cdot d\theta [/itex], are Joules.

Yet both these quantities are homongenous/ have same SI units.

Is it so wrong to quote torques in Joules? If so, why?

(And vice versa)

b.

the units for

**torque**,**[itex] \tau = r \times F [/itex]**,are N [itex]\cdot[/itex] m

and for

**work done by a torque**,[itex]W = \int_{\theta1}^{\theta2} \tau \cdot d\theta [/itex], are Joules.

Yet both these quantities are homongenous/ have same SI units.
