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. The higher the molecular … more
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 containing the toothpaste, the … more
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, it is necessary to … more
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, a light element, shows … more
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 reflected at all. When … more
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’ is as follows. \[ … more
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 point. (It is important, … more
Let’s measure my weight on several planets with the scale that we used on Earth. Newton explaining the gravity mathematically Every object has a gravitational field around it and attracts surrounding objects. The strength of this gravitational field is proportional … more
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 case, the main circuit … more
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 electric circuit consisting of … more
