 P: 14 as you all now torque in rotational motion has similarity with force in translational motion. but torque has the same unit as energy.it seems to me that there is a problem. Any explanation you have? (please ssmt different than " they are defined that way!!"
 Sci Advisor P: 905 In translational motion, work done (energy) is $$E=\int Fdx$$ In the same manner, in rotational motion, $$E=\int\tau d\theta$$ Since $$\inline{\theta}$$ is dimensionless, torque $$\inline{\tau}$$ has same units as energy. If it helps in keeping things apart, you can think of the units of torque as being say joules per radian.
