Capsim Success Measures RETURN ON EQUITY (ROE) Formula Description: What Does Return On Equity Tell You? Return on equity (ROE) is net profit divided by total equity. Return on equity tells you how effectively a company is using the dollars invested in it by stockholders. ROE is the most often quoted single statistic when describing a firm ’s performance. It is also one of the statistics considered to be most useful by stockholders. RETURN ON ASSETS (ROA) Formula Description: You determine

Antônia C. 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

The Physics of Baseball The sport of baseball has been around for over two hundred years‚ roughly since the 1800s. Invented by a man named Alexander Cartwright. It is known as “Americas past time.” Baseball is the national sport of the USA. The first baseball game played was in New York on June 19‚ 1845. And is played by thousands of people throughout the years. Much like any sport‚ it has changed with time. The first rulebook of baseball was issued in 1877. And it has been changing every year

Open-ended Investigation (mass and force) Aim: To show the relationship between Mass‚ the force acting on it‚ and acceleration by gathering data through investigations. Hypothesis: As Mass increases‚ Acceleration Decreases. Therefore‚ Acceleration is inversely proportional to mass. Introduction A force is a push or pull acting upon an object‚ as a result of its interaction with another object. In a state of motion‚ an object experiences different forces which influences its movement. There are many

ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

The Physics behind Flying Airplanes There are several aspects involved in the dynamics of airplane and how they become airborne. This report will address the main physics involved and mathematic formulae that prove how airplanes get above the ground from a small fighter jet to a massive Boeing 747. The necessities involved in keeping there massive weights in the air and the extreme forces needed to land these airplanes and bring them to a halt will also be explored. Firstly‚ the formula F
