September 25‚ 2013 Physics Tutorial Tonometry for Intra-Ocular Pressure In the linear non-elastic collision of the rod with the eyelid‚ there are 4 notable forces in action (Figure 1). 1. The force (or pressure) of the rod (rod/size of rod) exerted is equal and opposite to the force (or pressure) the cornea re-exerting pressure on the rod. 2. The force (or pressure) required to applanate a constant area of a cornea is equal and opposite to the force (or pressure) of the rebound on the

If we apply the highly successful kinetic theory of gases to a metal‚ consider as a gas of electrons (in fact‚ back in 1900 Drude constructed the theory‚ hence the Drude theory of metals)‚ and assume that the electron velocity distribution is given by the Maxwell-Boltzmann distribution‚ what would the most probable speed‚ average speed‚ and rms speed for electrons at room temperature

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Physics in My Daily Life “Write an essay of 1500 words‚ double spaced‚ in standard fonts ‚ giving credible references on the use of physics in your daily activity. You need to mention 5 or more activities where physics is used. Please follow the APA format.” As a senior in college‚ I lead a rather busy life. My days usually follow the same routine and pattern. I wake up at 7am everyday‚ so I am rather tired. To get going in the morning‚ I usually drink a cup of coffee. Then I attend my classes

Physics HL Aspects of Physics Case Study: Amusement Parks On the 26th of February‚ 2011 our class went on a field trip in order to analyse the aspects of physics present in amusement parks. I chose two aspects based on my favourite rides: ‘Kaboom’ (which works based on free-fall) and the roller coaster. The Physics of Roller Coasters How does a Roller Coaster work? Roller coasters have no engines (although many still tend to think they do) and are thus not propelled around the
