UNIT 1 Modern Physics 1.1 CLASSICAL PHYSICS Newtons laws of motion are the basis of the most elementary principles of classical physics. Equations based on these laws are the simplest and they are suitable for solution of simple dynamical problems‚ such as the motion of macroscopic bodies‚ Lagranges equations‚ Hamiltons equations and Hamiltons principle are also fundamental principles of classical mechanics‚ because they are consistent with each other and with Newtons laws of

Bonnie Inman. In 1977 she was 21 years old‚ the same age that I am today. Therefore‚ this the year of discussion. This year saw several advancements in technology‚ and brought forth visions of the future of this field. On June 11‚ 1977 the first Apple II computers went on sale‚ which became the world’s first most popular personal computer ("News and Events of 1977."). Furthermore‚ on August 12‚ 1977‚ NASA made its first space shuttle test flight with the Enterprise ("News and Events of 1977."). These examples

Physics End of Year Reflection Paper At the beginning of this course you were given some overarching enduring understandings and essential questions. These were: Overarching Enduring Understandings: Students will uncover and use appropriate scientific models to describe and quantify the nature and interactions of matter and energy. Students should understand that there is a network of rules and relationships that determine what will happen in a given situation Students

I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

To determine the heating and cooling curve of water Design: What we are going to do is investigate the phase changes and what the heating curve of water is. We are going to do this is by heating up 100ml of water on a Bunsen burner then adding ice cubes. Use a thermometer to measure the temperature every 30 seconds until it reaches a plateau. Hypothesis: As more time passes‚ the temperature of the water increases. Independent variable: Time Dependent variable: Changing water temperature

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing
