Albert Einstein Facts, Quotes, Relativity Theory, Science Information Albert Einstein was born on the 14th of March 1879 and died on the 18th of April 1955. Born in Germany to a Jewish family, Einstein made many contributions to the field of theoretical physics. Even when very young, Einstein showed great ability in both math’s and science. He was naturally curious and had a brilliant analytical mind. Einstein worked in a patent office evaluating patents for electromagnetic devices not long after he graduated. He produced perhaps one of the most famous equations ever: E = mc² (energy equals mass multiplied by the speed of light squared).

Determining the Net Force If you have been reading through Lessons 1 and 2, then Newton's first law of motion ought to be thoroughly understood. An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the statement of Newton's first law, the unbalanced force refers to that force that does not become completely balanced (or canceled) by the other individual forces. If either all the vertical forces (up and down) do not cancel each other and/or all horizontal forces do not cancel each other, then an unbalanced force exists. The existence of an unbalanced force for a given situation can be quickly realized by looking at the free-body diagram for that situation.

7 Free iPad Apps for Science Lessons Cross-posted from my other blog iPadApps4School.com I'm preparing to do a virtual presentation for a small district next month. My hosts asked for a list of some science apps that their middle school and high school students can use. This is part of the list that has free apps. The Bill Nye The Science Guy iPad app is a free iPad app on which students can watch Bill Nye videos, play games, and discover kitchen table science experiments to do at home with their parents. Kids - Albert Einstein Biography Albert Einstein was born as the first child of the Jewish couple Hermann and Pauline Einstein, nee Koch, in Ulm on March 14, 1879. When Albert’s grandmother saw him for the first time she is said to have cried continuously: "Much too thick! Much too thick!" But despite all fear the development of young Albert was a normal one.

The Meaning of Force A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction. Contact versus Action-at-a-Distance Forces For simplicity sake, all forces (interactions) between objects can be placed into two broad categories: 5 Fun Science Experiments for Kids Everyone knows science is awesome, but did you know you can do science right in your own kitchen? Ok, maybe you did, but if you're not sure where to start, we've got five really fun experiments that demonstrate the scientific principles of buoyancy, surface tension, density, chemical reaction and non-Newtonian fluid. Best of all, families can do these easy experiments with common, household items.

Thomas Edison Facts for KidsEasy Science For Kids Do you love your cell phone? How about movies or your digital camera? Thomas Edison invented early versions of these modern marvels. He also invented the electric light bulb. Drawing Free-Body Diagrams Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force.
