What is frame of reference and its types?
What is frame of reference and its types? There are two types of observational reference frame: inertial and non-inertial. An inertial frame of reference is defined as one in which all laws of physics take on their simplest form. In special relativity these frames are related by Lorentz transformations, which are parametrized by rapidity. What […]

Is the ruler drop test valid?
Is the ruler drop test valid? The ruler-drop test has acceptable test-retest reliability that compares favorably with computerized measures of reaction time. Which finger has the fastest reaction time? The fingers on the outside — i.e. the thumb and little finger — therefore react faster than the middle finger, which is exposed to the “cross […]
