History of Trigonometry Trigonometry is known to have been used during the ancient Egyptian period, which dates back before Christ. However, the founder of trigonometry is considered to be Battani. Battani lived in the Harran district of Şanlıurfa, Turkey, and used the concepts of sine and cosine while performing astronomical calculations. Furthermore, Battani was the first scientist to prove the
The History of Avogadro’s Law Avogadro’s Law was proposed in 1811 by the Italian scientist Amedeo Avogadro. According to his hypothesis: Three years later, Ampère published a paper with similar ideas, replacing the term “molecule” with “particle.” In 1826, Dumas determined atomic weights from the densities of gases, further supporting the validity of Avogadro’s Law. However, Avogadro’s hypothesis was largely
Motion in Two and Three Dimensions Moving beyond a single plane, we will examine the motion of objects in both a plane and in space. In this section, we explore the fundamental concepts of motion in two and three dimensions, delving into the dynamics of vector quantities such as position, velocity, and acceleration. 2D/3D Motion – Clean Layout Position
Basic Concepts Mechanics is a branch of science that studies the motion of objects and the reasons behind this motion. The part of mechanics that examines the motion of objects is called dynamics. Dynamics is divided into two main parts: kinematics and kinetics. What is One-Dimensional Motion? One-dimensional motion refers to the motion of an object in only one direction
Force Force is an effect that can be observed and experienced in many different ways in nature. By applying force to objects around us, we can change their motion, shape, or position. Understanding force is possible through simple interactions we encounter in daily life. Actions such as pushing, pulling, or breaking an object demonstrate the effects of force. Additionally, when
International System of Units (SI) In our daily lives, many things grow, shrink, or change over time. Every measurable and countable thing that undergoes such changes is referred to as a quantity. Quantities can be classified into various categories based on their field of use and the methods used for their study. These categories include Physical, Mathematical, Chemical, Biological, and
Emulsification is a process that occurs when a liquid is dispersed in fine droplets without dissolving in another liquid and is basically defined as the process of forming emulsions. Emulsification occurs more easily when the interfacial surface tension between two liquids is reduced. Surfactants (surfactants) support this process, enabling a more homogeneous and stable dispersion of one liquid in the
