Temperature and Reaction Rate

Temperature and Reaction Rate

Heat and molecular motion Every object is made up of atoms or molecules that are small particles that the eye can not see. These particles are constantly moved or oscillated themselves. This is called molecular motion. … more

Pascals Principle

Pascal’s Principle

Pascal’s Principle Pascal’s principle is as follows. “Suppose a closed tube filled with uncompressed fluid. Then, the pressure of this tube’s inside is the same everywhere.” For example, If you press any part of the tube … more

Zodiac Simulation

Zodiac

Zodiac The Ecliptic is the way the sun passes in the sky. zodiac means 12 constellations on the ecliptic. It is said that the zodiac was made in Babylonia around the 7th century BC. Constellation 1 … more

Projectile Motion

Projectile Motion

Projectile Motion When you throw an object, the object falls with a certain curve. The object performs a parabolic motion. This is a motion on a two-dimensional plane, not a straight line. To understand this movement, … more

Spectrum of Hydrogen Atom

Spectrum of Hydrogen Atom

Spectrum of hydrogen At the time of Rutherford’s experiments, chemists analyzed chemical components using spectroscopy, and physicists tried to find what kind of order in complex spectral lines. For example, a hydrogen arc tube containing hydrogen, … more

Total Internal Reflection and Optical Fiber

Total Internal Reflection and Optical Fiber

Total reflection and critical angle When light enters from a medium with a large refractive index to a medium with a small refractive index, the incident light does not pass through the boundary surface but is … more

Geometric Series Simulation

Geometric Series

Geometric sequence is The geometric sequence is a sequence in which each term has a constant(common) ratio to its preceding term. For example, the geometric sequence with the first term ‘a’ and the common ratio ‘r’ … more

R-L-C Serial Circuit Simulation

R-L-C Serial Circuit

RLC serial circuit Let’s consider a circuit in which a resistor (R) – an inductor (L) – a capacitor (C) are connected in series. Every moment, the current through the circuit is the same at every … more

Wheatstone Bridge

Wheatstone Bridge

Wheatstone Bridge Electronic measuring instruments like electronic scales detect and measure the resistance change of sensor material. To increase the sensitivity of measuring instruments, it is necessary to measure minute resistance values changes precisely. In this … more

LC Oscillator

LC Oscillator

There are fully charged capacitors. What happens if the capacitor draws current into the inductor? What is the similarity between physical vibration and electrical vibration? LC oscillator An LC circuit(also called a resonant circuit) is an … more

Capacitor Simulation

Capacitor

Capacitor A capacitor is an electronic component that temporarily holds charges. The stored charges can work while flowing again. Compared to a river flow, a capacitor can be likened to a dam that holds a river. … more
