## Dielectric

A capacitor can function if both conductor plates do not touch each other so that the electric charge does not move from one conductor to another. Likewise, so that the electric charge does not move from the conductor to the air, the space between the two conductors must be a vacuum. In the topic about …

## Electrical energy stored in capacitor

The capacitor is composed of two-conductor plates and between the two conductors, there is a dielectric. At first, the two conductors are electrically neutral. In order for the capacitor to function, each plate or sheet of the conductor must be electrically charged, where the amount of the electric charge in each conductor is equal but …

## Equation of capacitor circuit

A capacitor has a certain capacitance. If the required capacitance is not available, can be connected to two or more two capacitors to obtain the required capacitance. In order to properly connected the capacitor, it needs correct knowledge about the capacitor circuit ðŸ™‚ Before studying the capacitor circuit, first, understand the following symbols. Two vertical …

## Capacitance of capacitor

Definition of capacitance A small glass can contain a little water, while a large glass can contain more water. The larger the volume of glass, the more water that can be contained. So each glass has the capacity or size of the ability to contain water. Like glass, capacitors also have the ability to store …

## Addition of Vectors

1. Quantities of vector and scalar In addition to the fundamental and derived quantities, physical quantities can still be divided into two other types, namely scalar quantities and vector quantities. Quantities such as mass, distance, time and volume, are scalar quantities, quantities that only have magnitude but have no direction. Whereas magnitudes such as displacement, …

## Quantities of physics in the linear motion

1. Time interval When an object moves from one place to another, the object needs a certain time interval. The time symbol is t (time). The international system unit of time is second (s). 2. Distance and displacement Distance is the length of the path taken by an object. Distance is a scalar quantity, where …

## Uniform linear motion

Definition of uniform linear motion An object experiences uniform linear motion if the velocity of the object is constant. Velocity includes the magnitude and direction of velocity. Direction of velocity = direction of displacement = direction of movement. The direction of the velocity of a constant object = the direction of motion of a constant …

## Nonuniform linear motion

Definition of nonuniform linear motion Nonuniform linear motion is motion at constant acceleration. In other words, nonuniform linear motion = motion with the magnification of acceleration is constant and the direction of acceleration is constant. Direction of acceleration is constant = direction of velocity is constant = direction of displacement is constant = direction of …

## Free fall motion

In everyday life, we often see objects that experience free-fall motion, for example, the motion of fruit falling from a tree, the motion of objects that fall or are dropped from a certain height. Why do objects experience free-fall motion? If observed at a glance, the object experiencing free fall as if it has a …

## Uniform circular motion

In everyday life, we often encounter objects that move in a uniform circular motion. One example of an object that undergoes uniform circular motion is the second needle, the minute needle, and the clock needle on the analog clock. The second needle always rotates at an angle of 360o for 60 seconds (one minute) or …
