Wheels are also a factor in drag as when they spin they cause friction. Science of Cycling: Aerodynamics & Wind Resistance | Exploratorium. (n.d.).

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

so that it lands safely. Background Obviously I built this device with some prior knowledge to physics and how to make this device successful. I have learned several equations about force‚ work‚ power‚ height‚ speed‚ velocity and a lot more. So with force‚ f=ma‚ then I can easily discern what the force of the egg will be. Also‚ since I know all of these things‚ than I can figure out all of the physics with just the equations. Also I learned‚ with these things‚ that if the force of the egg doesn’t

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis?
