Investigating the effect of discomfort on reaction time Purpose and method The purpose of this investigation was to investigate the effect of discomfort on reaction time in humans‚ measured by dropping a ruler into a subject’s hand. Discomfort was caused by a bowl of ice. Background information Information is carried from the sensory receptors to the central nervous system and back the to effectors by means of nerves. When a number of different processes are involved (a situation informally

relates to Hooke’s law. Hooke’s law states “Force is directly proportional to the displacement from the equilibrium position and acts in the opposite direction of the displacement”. Method For this assignment I am going to try and verify the kinematic simple harmonic motion of a pendulum and compare physical measurements taking with the theory of SHM to verify if the theory is correct. To achieve this I am going to attach a plumb bob to a piece of string suspended from a clamp to allow it to oscillate

1824: Peter Roget presented his paper ’The persistence of vision with regard to moving objects’ to the British Royal Society. 1831: Dr. Joseph Antoine Plateau (a Belgian scientist) and Dr. Simon Rittrer constructed a machine called a phenakitstoscope. This machine produced an illusion of movement by allowing a viewer to gaze at a rotating disk containing small windows; behind the windows was another disk containing a sequence of images. When the disks were rotated at the correct speed‚ the synchronization

Introduction: Anterior cruciate ligament (ACL) injuries of the knee are common in sports that require jumping and rotational movements such as‚ gymnastics‚ basketball‚ soccer‚ volleyball‚ football‚ and handball (Gilchrist‚ 2008). Treatment for an ACL injury is expensive‚ requires extensive amounts of rehabilitation‚ and increases the risk of early osteoarthritis in individuals (Meeuwisse & Emery‚ 2010; Waldén et al.‚ 2012). The financial costs associated with ACL injuries are an estimated $3 billion

Discussion: The objective of the first article investigated stride length‚ stride frequency‚ ground contact‚ and flight times for three different conditions; running barefoot‚ running in minimalist shoes‚ and running in conventional running shoes. The results of the study showed that the stride duration in barefoot running was less than the stride duration in the traditional or minimalist shoe running. Overall the results also showed that the traditional shoes had a longer stride duration when

Introduction Career in mechanical engineering involves grappling with various aspects of the technical and practical work. The job of a mechanical engineer involves widespread handling of machines and components which have a direct relation with power by producing it‚ transmitting it or even making use of power. The major concern of mechanical engineers is bent towards ways and mechanisms through which natural energy sources are converted into uses of practical nature. As part of their work‚ mechanical

Stride Rate and Length Although strides vary greatly among runners‚ a few studies have worked to quantify differences in stride rate between barefoot and shod runners. They have concluded that an elite shod runner usually has a stride frequency between 170-180 steps per minute even at low speeds such as 2.75 m∙s-1. On the other hand‚ nonelite runners often fall in the range of 150-160 steps per minute at similar speeds. Barefoot or minimally shod runners are often characterized by shorter strides
