## New Curriculum Math Note of Current Electricity

New Curriculum Math Note of Current Electricity. An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. […]

## Math Solution of Magnetic Effect of Electric Current and Magnetism

Math Solution of Magnetic Effect of Electric Current and Magnetism. When electric current flows through a wire wound around an iron bar, the bar behaves like a magnet. This magnet […]

## New Curriculum Physics Note of Current Electricity

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can […]

## Static electricity

Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker […]

## Gravitation

Gravitation, or gravity, is the natural phenomenon by which physical bodies appear to attract each other with a force proportional to their masses. It is most commonly experienced as the […]

## Elasticity

When an elastic material is deformed due to an external force, it experiences internal forces that oppose the deformation and restore it to its original state if the external force […]

## Vector

Vectors Euclidean vector, a geometric entity endowed with magnitude and direction as well as a positive-definite inner product; an element of a Euclidean vector space. In physics, euclidean vectors are […]

## Math Solution of Linear Motion

Math Solution of Linear Motion Linear motion is motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of […]
