The Theory of Relativity, For Kids - Trending Sideways. So you want to understand the theory of relativity, and you’re a kid?

No problem. Let’s get started. (If you’re a parent looking for some activities to help teach your kid, consider ordering Albert Einstein and Relativity for Kids: His Life and Ideas with 21 Activities and Thought Experiments. And if you’re an adult who just wants to understand relativity, there’s no shame in reading on.) Light Always Moves the Same Speed A long time ago, scientists wanted to figure out how fast the earth was moving through space. Think about it like this. And, of course, if you turned around and ran toward the rain, it would hit you even harder than if you stood still. Back then, scientists thought that light acted like rain drops in a rain storm.

It shows that the scale on the left was measuring the force of gravity (weight) not mass. On earth the spring was standardized to read 100g at sea level. Instructional Materials in Physics. Instructional Materials in Physics Below are the CLN "Theme Pages" which focus on specific topics within Physics.

CLN's theme pages are collections of useful Internet educational resources within a narrow curricular topic and contain links to two types of information. Students and teachers will find curricular resources (information, content...) to help them learn about this topic. In addition, there are links to instructional materials (lesson plans) which will help teachers provide instruction in this theme. Bubbles Theme Page. The Electromagnetic Spectrum. The Electromagnetic Spectrum. Force Equals Mass Times Acceleration: Newton's Second Law. Kinetic and Potential Energy. Thermodynamics. 1st Law of Thermodynamics The First Law of Thermodynamics simply states that energy can be neither created nor destroyed (conservation of energy).

Thus power generation processes and energy sources actually involve conversion of energy from one form to another, rather than creation of energy from nothing 2nd Law of Thermodynamics The second law is concerned with entropy, which is a measure of disorder. The second law says that the entropy of the universe increases Absorbed Solar Radiation Solar radiation absorbed by various materials. Physics.

Dimensions Home. A film for a wide audience!

Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed! Background information on every chapter: see "Details". Click on the image on the left to watch the trailer ! Biographies. Chapter 1: Magnetism - Magnetorheological fluids, homemade ferrofluid. Magnets and Magnetism We have all played with magnets.

A pair of magnets by itself makes a wonderful toy. Today's magnets are even better than the best ones I remember playing with as a child. Physics Flash Animations. We have been increasingly using Flash animations for illustrating Physics content.

This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page.

The Animations There are 99 animations listed below. National High Magnetic Field Laboratory - The Magnetic Field Around a Wire Tutorial (I) Symmetry - Archive: Explain it in 60 Seconds.
