Psychophysiology measures exist in three domains; reports, readings, and behavior. Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, or measures of interoceptive visceral awareness such as heartbeat detection. Merits to self-report are an emphasis on accurately understand the participants subjective experience and understanding their perception; however, its pitfalls include the possibility of participants misunderstanding a scale or incorrectly recalling events. Physiological responses also can be measured via instruments that read bodily events such as heart rate change, electrodermal activity (EDA), muscle tension, and cardiac output. Many indices are part of modern psychophysiology, including brain waves (electroencephalography, EEG), fMRI (functional magnetic resonance imaging), electrodermal activity (a standardized term encompassing skin conductance response, SCR, and galvanic skin response, GSR), cardiovascular measures (heart rate, HR; beats per minute, BPM; heart rate variability, HRV; vasomotor activity), muscle activity (electromyography, EMG), electrogastrogram (EGG) changes in pupil diameter with thought and emotion (pupillometry), eye movements, recorded via the electro-oculogram (EOG) and direction-of-gaze methods, and cardiodynamics, recorded via impedance cardiography. These measures are beneficial because they provide accurate and perceiver-independent objective data recorded by machinery. The downsides, however, are that any physical activity or motion can alter responses, and basal levels of arousal and responsiveness can differ among individuals and even between situations. Finally, one can measure overt action or behavior, which involves the observation and recording actual actions, such as running, freezing, eye movement, and facial expression. These are good response measures and easy to record in animals, but they are not as frequently used in human studies.

The force (F) experienced by a foil is determined by its area (A), fluid density (), velocity (V) and the angle of the foil to the fluid flow, called angle of attack ( {\displaystyle \alpha } ), where: F A V 2 = f ( R n , ) {\displaystyle {\frac {F}{\rho AV^{2}}}=f(R_{n},\alpha )} The force has two parts that normal to the direction of flow is lift (L) and that in the direction of flow is drag (D). Both can be expressed mathematically: L = C L 1 2 V 2 A {\displaystyle L=C_{L}{\tfrac {1}{2}}\rho V^{2}A} and D = C D 1 2 V 2 A {\displaystyle D=C_{D}{{\tfrac {1}{2}}\rho V^{2}A}} where CL and CD are lift coefficient and drag coefficient respectively. Each coefficient is a function of the angle of attack and Reynolds number. As the angle of attack increases lift rises rapidly from the no lift angle before slowing its increase and then decreasing, with a sharp drop as the stall angle is reached and flow is disrupted. Drag rises slowly at first and as the rate of increase in lift falls and the angle of attack increases drag increases more sharply. For a given strength of circulation ( {\displaystyle \tau } ), Lift = L = V {\displaystyle {\mbox{Lift}}=L=\rho V\tau } . The effect of the flow over and the circulation around the aerofoil is to reduce the velocity over the face and increase it over the back of the blade. If the reduction in pressure is too much in relation to the ambient pressure of the fluid, cavitation occurs, bubbles form in the low pressure area and are moved towards the blade's trailing edge where they collapse as the pressure increases, this reduces propeller efficiency and increases noise. The forces generated by the bubble collapse can cause permanent damage to the surfaces of the blade.
