Electric motors are everywhere! In your house, almost every mechanical movement that you see around you is caused by an AC or DC electric motor. By understanding how a motor works you can learn a lot about magnets, electromagnets and electricity in general. On this page we hope you will learn what makes an electric motor spin. 
    An electric motor is all about magnets and magnetism.  A motor uses magnets to create motion.  If you have ever played with magnets you know the law of magnets:...

    A simple generatoris similar to an electric motor.
With a motor, we put electrical energy in and get rotational energyout,
with a generator we put rotational energy in and get electrical energy out.

As with the motor, the current direction changes
with each half turn of the generator.
The generator produces alternating current
because slip rings are used in place of a split - ring commutator.

Skeletons can be divided into two main types based on the relative position of the skeletal tissues. When these tissues are located external to the soft parts, the animal is said to have an exoskeleton. If they occur deep within the body, they form an endoskeleton. All vertebrate animals possess an endoskeleton, but most also have components that are exoskeletal in origin. Invertebrate skeletons, however, show far more variation in position, morphology, and materials used to construct t...

     Plant cells are cells that are in plants. Plant cells are like animal cells, but they have a cell wall and chloroplasts. Here's a labeled picture of a plant cell. You will see all the main parts of the cell. Listed below are definitions of those words. Read on to learn more about photosynthesis.

A very special process that takes place inside of the chloroplasts in plant cells is called photosynthesis (foto-SIN-thi-sis). Photo means "light" and synthesis means " putting things togeth...

The trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications.

The most familiar trigonometric functions are the sine, cosine, and tangent. The sine function takes an angle and tells the length of the y-component (rise) of that triangle. The cos...

    Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia. Most cells, both animal and plant, range in size between 1 and 100 micrometers and are thus visible only with the aid of a microscope.

 

The lack of a rig...

The Digestive Process:

The start of the process - the mouth: The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).

On the way to the stomach: the esophagus - After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rh...
