Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance

In the Tumble Buggy Lab‚ my partners and I used several different methods to calculate the velocity of a Tumble Buggy. The methods we used were a meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor

INTERPRETATION OF RESULTS: This experiment circles around with the Newton’s second condition of equilibrium in rotational motion. It describes by net torque acting on a body which is zero. The ability of the body to rotate in a certain direction is varied according on how much torque is applied. To prove that‚ a beam that is subjected to two forces is balanced by adjusting the perpendicular distances. When applied force is weight‚ modification in masses added is also done. Once equilibrium is achieved

Newton`s Second Law – Lab Report Name: Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude

Sample Short Lab Report By Charles M Borener Jr April 24‚ 2009 Kinetic Friction Experiment #13 Joe Solution E00123456 Partner - Jane Answers PHY 221 Lab Instructor – Chuck Borener Thursday‚ 11 AM – 1 PM Lecture Instructor – Dr. Jacobs Abstract In this experiment‚ we test factors which effect friction. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface effects friction. We found that the surface area of the block did not change

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction
