DC-DC converters Step-up and step-down circuits are types of DC-DC converters that convert an input voltage to a desired output voltage. Step-up circuits convert a low input voltage to a higher output voltage, while step-down circuits … more
Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric … more
Reaction time It takes a while for a person to react to a stimulus. This is because the signal needs time to be transmitted and processed. The reaction time for the three stimuli of visual, auditory, … more
Movement of the planets of the solar system The planets in the solar system receive gravity from the Sun and revolve around it due to this gravity. The following is a table of the orbital radius … more
This app is Web-based software that converts video footage of an object’s motion into multi-flash photography. This program analyzes the movement of objects captured on video frame by frame. It may not work on Apple devices … more
Direction of the Lorentz force Conductors in which current flows in a magnetic field are forced to move. The direction of this force is perpendicular to the current and the magnetic field, respectively. More precisely, we … more
Range X min X max Y min Y max This app is a web-based software that analyzes the motion of objects recorded in video frame by frame. This program analyzes the movement of objects captured on … more
Conduction The ‘conduction’ of heat is how heat is transferred by moving particles that make up an object to neighboring particles. Heat can be transferred even if the particles do not move, mainly by vibration or … more
QR Scanner You can easily scan a QR code even if your camera does not have a scanning function. Click on the scan result in the center of the screen to go directly to the URL.
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
Particle movement according to temperature The matter around us is made up of tiny particles constantly moving. The particles move more actively as the temperature increases. Water particles move more actively in hot water than cold … more
