Radionuclide Imaging and Therapy (AQA A-Level Physics): Flashcards

No heat enters or leaves the system

$\alpha = \frac{\Delta \omega}{\Delta t}$

$L = I \omega$

$\Delta U = Q - W$

$I = mr^2$

$E = \frac{1}{2} I \omega^2$

$\tau = F \times r$

Temperature remains constant

Constant in closed system with no external torque

No heat engine can be 100% efficient
