TOPIC: Spring Mass Oscillator OBJECTIVE: To determine the spring constant (K)‚ using mass system. APPARATUS: STEEL RULE SPRING STOP WATCH TAPE MEASURE SLOTTED MASS THEORY: In classical mechanics‚ a harmonic oscillator is a system which ‚ when displaced from its equilibrium position‚ experience a restoring force‚ F‚ proportional to the displacement‚ X‚ according to Hooke’s Law; F = – KX = mα ………………………………….

The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes that’re required to replicate this study.

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do

Abstract Ernest Rutherford’s Gold Foil Experiment was a major stepping stone one the way to discovering what the atom was really made up of. From the beginning of his research with alpha particles to his discovery of the atomic nucleus‚ Rutherford made many contributions to the microscopic world of the atom. The Rutherford Experiment‚ otherwise known as the Gold Foil Experiment‚ was the crown of his achievements‚ and it was during this experiment that he discovered the atomic nucleus. (Aydin &Hanuscin

Experiment 7 General Safety Considerations 1. 1-Butanol and 1-bromobutane are toxic and irritating. Avoid all contact by constantly wearing goggles‚ gloves and working in the hood. Neither of these compounds can be poured down the drain. Like all products‚ 1-bromobutane should be turned in to your TA in a labeled vial. Any excess butanol should be discarded in non-halogenated waste. 2. H2SO4 is extremely corrosive. In very diluted form it can be poured down the drain‚ all other precautions

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that

involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the experiment included a gram scale‚ thermocouple‚ Styrofoam cup‚ glass beakers

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested.
