Charge Conservation
In the serial circuit, The current is the same everywhere. In the parallel circuit, The current splits up when it comes to a branch. The current in all the branches adds up to the current in the main part of … more
Electroscope
Electroscope Using an electroscope, you can determine whether an object is charged or the polarity of the charge. When the (+) charged body is close to the metal plate, the metal foil’s free electrons are attracted to the metal plate, … more
Electrostatic Induction
What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more
Electrostatic induction (the viewpoint of metal bonding)
What happens when the charged body is close to the conductor? Electrostatic induction is a redistribution of electrical charge in an object caused by the influence of nearby charges. In the presence of a charged body, an insulated conductor develops … more
Conductor and Insulator
What happens when the charged body is close to the conductor and insulator? ConductorElectrostatic induction is a redistribution of electrical charge in an object caused by nearby charges’ influence. In the presence of a charged body, an insulated conductor develops … more
Superposition and Interference
Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. It creates constructive interference or destructive interference.
Newton Ring
The Newton ring The interference of two reflections causes Newton rings. We can observe the Newton Rings when light is reflected from a plano-convex lens of a long focal length placed in contact with a plane glass plate. A thin … more
Voronoi Diagram Drawing
A Voronoi diagram is a partitioning of a plane into regions based on the distance to points in a specific subset of the plane. That point set is specified beforehand. And regions(Voronoi cells) are consisting of all points closer to … more

Spring Pendulum(Vertical)
This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of movements that repeated the same oscillation. Like below, shaky or suspended objects are doing this oscillation. Clock pendulum An object suspended in … more
Force on Inclined Plane
Gravity acts on all objects. Suppose an object is placed on an inclined plane. This object is subjected to a force that slips downward by gravity. If the slope is θ, then the magnitude of this force is the product … more
