A machine is a tool used to make work easier. Simple machines are simple tools used to make work easier. Compound machines have two or more simple machines working together to make work easier. In science, work is defined as a force acting on an object to move it across a distance. Pushing, pulling, and lifting are common forms of work. Furniture movers do work when they move boxes. Gardeners do work when they pull weeds. Children do work when they go up and down on a see-saw. Machines make their work easier. The furniture movers use a ramp to slide boxes into a truck. The gardeners use a hand shovel to help break through the weeds. The children use a see-saw to go up and down. The ramp, the shovel, and the see-saw are simple machines. Inclined Plane A plane is a flat surface. For example, Read More

About Rainbows

Votes:0
What is a rainbow? Author Donald Ahrens in his text Meteorology Today describes a rainbow as "one of the most spectacular light shows observed on earth". Indeed the traditional rainbow is sunlight spread out into its spectrum of colors and diverted to the eye of the observer by water droplets. The "bow" part of the word describes the fact that the rainbow is a group of nearly circular arcs of color all having a common center. Where is the sun when you see a rainbow? This is a good question to start thinking about the physical process that gives rise to a rainbow. Most people have never noticed that the sun is always behind you when you face a rainbow, and that the center of the circular arc of the rainbow is in the direction opposite to that of the sun. The rain, of course, is in the direc Read More

CHEMystery: Thermodynamics

Votes:0
Thermodynamics Return to the Main CHEMystery Page What is Thermodynamics? Thermodynamics is the branch of science which studies the transformation of energy from one form to another. Chemical thermodynamics looks at the energy transformations which occur as a result of chemical reactions. The questions that chemical thermodynamics asks are: How much heat is evolved during a chemical reaction ("thermochemistry")? What determines the direction of spontaneous chemical change? For example, if you put a flame to a 2:1 mixture of H 2 and O 2 there is an almighty bang and the reaction proceeds spontaneously to products, i.e. without any further supply of external energy. Why does it not happen that water spontaneously goes to H 2 and O 2 when we put a lit taper to it under the same conditions? Wh Read More

energy I

Votes:0
Energy I Energy is the ability of an object to cause change. The energy of an object in motion is called kinetic energy. The word "kinetic" was derived from the Greek word for motion. The greater the mass of a moving object, the greater is its kinetic energy. A 4,000 pound Cadillac moving at 60 miles per hour has more energy that a 2,000 pound Subaru. Kinetic energy is also related to speed. The greater the speed, the greater the kinetic energy. For example, a 2,000 pound Subaru moving at 120 miles per hour has more kinetic energy that a 4,000 pound Cadillac moving at 5 miles per hour. Potential energy is the ability of an object to cause change because of its position. When two things are pulling on each other, the further apart you separate them, the greater the potential energy.

Earth is a complex of active physical and biological systems which interact and influence one another and change in response to energy in its various forms. There are various sources and forms of energy on Earth; some exert their influence naturally and others do so through human intervention. Energy cannot be destroyed but it can be (and constantly is) converted from one form to another. 1. What is the most important source of energy for Earth? The Sun. Energy radiating from our closest star - the Sun - provides the natural power that fuels most of the physical and biological processes important to life. These processes include the mo Read More

The first two installments in the series are now available. Bending Spacetime in the Basement We live our entire lives within the Earth's gravitational field, yet rarely if ever do we experience the universality of gravitation: that every object in the universe attracts and is attracted by every other. This page presents a "basement science" experiment which reveals the gravitational attraction between objects less than a kilogram in mass. Knowledge in antiquity suggesting gravitation was universal is discussed, and the feasibility of an experimental test using only materials and technique Read More

Kinetic Theory I

Votes:0
Kinetic Theory I This Java applet simulates a 2 dimensional gas of hard spheres. It illustrates several important concepts in statistical mechanics/kinetic theory, such as: mean free path and average time between collisions, the approach to thermal equilibrium and the Maxwell-Boltzmann speed distribution, and the question of macroscopic irreversibility vs. microscopic reversibility. To use the applet, enter a number in the text field, click "Set", then click "Run." The "molecules" are spheres of radius one pixel (the default value; you can change the radius to two pixels by clicking in the "Make particles bigger" box) and do not interact except when they come in contact; then they scatter elastically. The small box on the right shows the distribution of speeds as the collisions take place. Read More

Rainbow Facts

Votes:0
Questions about R a i n b o w s People have been asking questions about rainbows since the beginning of time. One question frequently asked is, how far away is that rainbow? That is a tough one. How far away are the raindrops that produce it? It is hard to judge how far away a rain cloud is; especially if it's moving. The rainbow's distance extends from the nearest to the farthest raindrops that contribute any part of the colored light. The closest of these raindrops may be miles away. In the case of water spray from a lawn sprinkler in which a rainbow appears, you can reach right in and "touch it"....or so it seems. Many questions are unique to one's cultural history. Where is that pot of gold? That is a good question too. The idea that a pot of gold can be found at the rainbow' Read More
