Matthew Mannetta Simple Harmonic Motion Lab Report Introduction Simple harmonic motion is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s Law. In this lab‚ we will observe simple harmonic motion by studying masses on springs. In the first part of this lab‚ you will determine the period‚ T‚ of the spring by observing one sliding mass that is attached to two springs with the spring constant k‚ and attached to a hanging mass by a string

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the

To distinguish endospores‚ free spore‚ and vegetative cells Theory: A dormant form of bacterium that allows it to survive poor environmental conditions are called endospores. Their tough outer covering is made of keratin and is also the reason they are resistant to heat and chemicals. The strength of keratin also makes it resist

Abstract This experiment was carried out to perform staining methods on microbes‚ explain the mechanisms of staining‚ namely‚ simple staining‚ and learn how to use the microscope. The experiment setting was kept as sterile as possible when conducting the experiment. The microbes under the microscope were drawn out and labelled. In conclusion‚ different staining techniques are used to determine the presence of certain exterior structures of the bacteria like the cell envelope or just to identify

Abstract The glass transition temperature of polymethylmethacrylate ( PMMA‚ Perspex) is measured using static and dynamic method while the glass transition temperature of rubber of different size is measured using only dynamic method. The glass transition temperature Tg of Perspex is found to be 90°C using the static method and 160°c using the dynamic method. On the other hand‚ the Tg of rubber is found to be -30°C. Introduction Perspex is a type of amorphous polymer and has the following

Through processes know as wet mounts and simple stains‚ observing living microorganisms through a compound microscope can generate a clearer understanding of their appearances and movements. Microorganisms are living things that for the most part cannot be seen through the naked eye. They live on and among humans‚ as well as plants‚ animals‚ and all that is a part of the Earth. Harmless as most seem to be to humans‚ microorganisms are an important relevance of study for human interest in varied perplexities

There are several types of diffusion‚ but for the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution

Simple Sugars Lab Emerson: Hallie: Background: Benedicts solution is a chemical solution that changes color in the presence of glucose and other reducing sugars. It is a mixture of sodium or potassium citrate‚ sodium carbonate‚ and copper sulfate. It changes from its normal blue color to an orange‚ red‚ or yellow. it changes based on the amount of sugar used.

PCS125 Lab – The Simple Pendulum Objective and Background Objective: The Objective of this experiment is to examine the simple harmonic motion and to determine the value of the acceleration due to gravity from the analysis of the period of the simple pendulum. [1] Background: There are three equations that will be used to calculate the period of motion of the simple pendulum. They are the slope of the line of the graph of T² against L‚ and the gravity of the pendulum motion. The period of
