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

The Theory of Relativity, For Kids - Trending Sideways

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.

What is the Difference between Mass and Weight?

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.

Instructional Materials in 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.

They were written by educators with input from scientists, researchers, students, and teachers. Students, teachers, and parents are encouraged to work together to begin an exploration of concepts that help us learn about how we see our world. HPS 0410 Einstein for Everyone.

Chapter 1: Magnetism - Magnetorheological fluids, homemade ferrofluid

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.

Physics Flash Animations

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.
