Application Of Physics In Medicine Medical physics is generally speaking the application of physics concepts‚ theories and methods to medicine. A medical physics department may be based in either a hospital or a university. Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology

------------------------------------------------- Motorcycles are Safer than Cars Everyone knows that in a crash motorcycle riders usually come off worse than car drivers. Riders avoid some problems‚ like being trapped in a burning or sinking car‚ but in general an accident that dents a car can put a motorcyclist in hospital. However motorcycle fear is often based on rumor or reports‚ not actual experience. It is guilt by association. Guilt by Association A friend once told me she didn’t like

I. Introduction Crash‚ boom‚ bang! In an instant‚ a car accident can change a person’s life forever. Each year‚ many unsuspecting drivers‚ passengers‚ and pedestrians are killed on the roads of the United States. The main question we ask ourselves is why? Are people killed because of high speed crashes? Did the airbags not deploy at the proper time? Were the roads in acceptable conditions? Unfortunately‚ we can not always determine the causes of all accidents‚ simply because we were not on

tucks her arms in‚ she will spin much more rapidly. By moving her mass closer to the axis‚ she reduced her moment of inertia. Many practical applications for this experiment exist. Car manufacturers study it carefully to determine how quickly a car will spin out of control. Here‚ a higher moment is created such that the car is less likely to lose control in a spin. Many sports also use the concept‚ as in the example of the skater. Divers use this so they can use the lowest moment of inertia and fastest

The Smart Car The Smart car was introduced in 1994 between Mercedes-Benz and the Swiss manufacturer of Swatch watches and was unveiled in 1997. The car was named for “Swatch‚ Mercedes and art.” The Smart car only measures in at 8-feet-8-inches long and is 5-feet-1-inch wide. More than 95% of the components are recyclable. The Smart car is priced in at three different versions. The Pure is at the base level and starts at $11‚590. The Passion is decked out and is most popular and starts at $13

Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla Roadster car accelerates

Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed
