Integral in physics
Definite integral In the 2D coordinate plane, a definite integral is a way to find the area of a graph. In a rectangle, the only simple way to get the area is the multiplication of width and height. If the … more

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 containing the toothpaste, the … more
Pressure and Pressing Area
The force applied per unit area is called pressure. If the force applied to any two points is the same, the larger the area, the smaller the pressure. Conversely, the smaller the area, the greater the pressure. This is why … more
Area of Circle
How to calculate the area of a circle If you cut the circles and stick them together, they gradually become more rectangular. In this rectangle, the width is half of the circumference, and the height is the radius. Therefore, The … more
