Fundamental physics concepts

Let’s look at one other wave property of light. Light travels in transverse waves and this property is demonstrated by a phenomenon called polarization. Polarization means that the waves of light are restricted in their direction of vibration. Think of a horizontal string that you shake from one end. If you shake the string up and down, you will get up and down, or vertical, waves. If you shake the string back and forth, you will get horizontal waves. In this way, the string is said to be polarized

Aim - To find how much energy is released by setting the food alight from a Bunsen burner and putting the ignited food under a test tube with 20mL of water in the test tube. Hypothesis - My hypotheses is that the chip, which has the most flavouring on it will increase the temperature of the water inside the test tube, when the chip is ignited and held under the test tube. Materials - 2x Heat proof mats. 1 Bunsen burner. 1x Retord stand & clamp. 1x Measurement cylinder. 1x Test tube

All things begin somewhere, including States of Matter. God created these substances and had people discover them. The process of one of the States of Matter, Gas, was discovered by an Irish natural philosopher named Robert Boyle. He had many other accomplishments, including advocating for the scientific method. During his time on earth, he wrote a fairly popular book and had an interest in alchemy, the study of turning metals into gold. Boyle was a curious person and wasn’t going to settle for an

Aptanta 9B Mr. Anthony Science- Physics The difference in density between salt water and tap water I. Problem: • Will an egg float on fresh water or tap water? II. Background Information: Density is a measurement of how matter is in a certain volume/object. It is basically the compactness of an object. If the molecules are closer to each other, therefore it’s denser. If you compare a cuboid Styrofoam and a cuboid metal, the metal would weigh heavier because it is denser. The denser the object,

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form, Efficieny- e.motor=85%, combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

All About the Cartwheel Galaxy written by: vancepreed•edited by: George Adcock•updated: 9/28/2011 The Cartwheel Galaxy is the result of a collision between two galaxies. Find out more about it in this Bright Hub article. Fritz Zwicky and the Cartwheel Galaxy In 1941, the astronomer Fritz Zwicky discovered one of the more interesting celestial objects in the Cartwheel galaxy; its unique shape earned it its name. The galaxy belongs to a group of galaxies that make up the Sculptor constellation. It

I. Introduction A. Purpose: The purpose of this lab was to find the densities for water, two liquids, and two solids and compare their densities with the density of water to find their specific gravities. B. Equipment i. Electronic balance: An electronic balance is an instrument that measures the mass of an object placed on the balance in grams and automatically rounds the measurement to two decimal places. ii. Graduated Cylinder: A graduated cylinder is an instrument that measures the volume of

The objective of this laboratory experiment is to determine the specific rotation and the concentration of a known substance (e.g maltose) in a solution by using polarimetry technique. The second objective is to identify the type of carbohydrate by measuring its specific rotation before and after mutarotation. Only the compounds that contain a chiral carbon atom have the ability to rotate the plane of polarization of polarized light. The optical rotation is the angle which the light is rotated when

SW. Once values are derived, an error can be computed from the know values of water. In further examination, students will be asked to decipher the identity of the unknowns by researching similar characteristics of various fluids. In doing this, concepts of fluid properties are reinforced, while providing

In a suspension, it is easy to see the particles. These particles can be touched. It is impossible to see the particles in a true solution, even with a microscope. The particles can not be felt. It is possible to see the particles in a colloidal solution with a microscope, but they are not as big as the particles in a suspension. If a colloidal solution is touched it will appear solid, but pressing a finger in slowly it will cause the material to flow like fluid. This is known as a non-Newtonian
