Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time‚ as we go to work or school‚ participate in sports or even wander around our homes. If we never changed our own motion‚ we would never make it out of bed in the morning. The study

PHYSICS INTERNAL ASSESSMENT How to measure the density of water using graphical method? Name: Chia Yee Xin Candidate Number: Session: October 2014 School: Sri KDU International School Research Question: To measure the density of water using graphical method. Introduction: Water is the most abundant compound on the Earth and it covers about 70% of the Earth’s surface. Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of

Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

Effecting the Reaction Rate in Enzymes in Plants and Animals Problem- How do variables temperature and surface area affect the rate of reaction occurring in the enzyme? Information- Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes can be found in both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat

SPH4U-B 4 Circular Motion Physics SPH4U-B Lesson 4 Introduction Transportation has undoubtedly advanced. Not only have vehicles changed‚ but the means by which people can get themselves to and from different locations has changed as well. Maps and compasses now take a backseat to the Global Positioning System (GPS). Access to the GPS is now very widespread; 24 satellites above our atmosphere are used to send and receive information in order to accurately determine locations of

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚
