Projectiles

A projectile is any object that is thrown, shot, or launched into the air, and that moves along a ballistic trajectory. Projectiles are subject to the force of gravity, which causes them to follow a curved path known as a parabola. The motion of a projectile can be described by its initial velocity, angle of…

Cartesian coordinates only

Cartesian coordinates are a system of describing the position of a point in space using three numbers, typically denoted as (x, y, z). The x-coordinate represents the distance from the point to the yz-plane (a plane perpendicular to the x-axis), the y-coordinate represents the distance from the point to the xz-plane (a plane perpendicular to…

Kinematics in one

Kinematics in one dimension refers to the study of motion of an object in a straight line. It involves analyzing the position, velocity, acceleration, and time of an object as it moves along a single axis. Kinematics is an important branch of physics that forms the basis of many other fields, such as mechanics and…

Ammeter

An ammeter is an instrument used to measure the electric current in a circuit. It is typically connected in series with the circuit so that all of the current flows through it. The ammeter measures the flow of electrical charge in amperes (A) and is usually calibrated in milliamperes (mA) or microamperes (μA) for smaller…

Determination of g using simple pendulum

The period of a simple pendulum can be used to determine the acceleration due to gravity, g. The formula for the period T of a simple pendulum is: T = 2π√(L/g) where L is the length of the pendulum and g is the acceleration due to gravity. To determine g using a simple pendulum, follow…

Dimensional Analysis

Dimensional analysis is a mathematical technique used to check the correctness of equations and to convert one unit of measurement to another. It involves analyzing the dimensions of physical quantities involved in a problem and setting up equations based on these dimensions. In dimensional analysis, physical quantities are expressed in terms of fundamental dimensions such…

Carbonyl (Aldehyde and Ketone)

Carbonyl compounds are organic molecules containing a carbonyl group, which is a functional group consisting of a carbon atom double-bonded to an oxygen atom. There are two main types of carbonyl compounds: aldehydes and ketones. Aldehydes have the carbonyl group at the end of a carbon chain, while ketones have the carbonyl group in the…

Detection of elements (N, S, halogens)

The detection of elements such as nitrogen (N), sulfur (S), and the halogens (fluorine, chlorine, bromine, iodine, and astatine) can be accomplished through various chemical and instrumental methods. Here are a few examples: Instrumental methods such as atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), and X-ray fluorescence (XRF) can also be used…

Soaps

Soaps are a type of cleansing agent that are typically used for washing the body or other surfaces. They are made by mixing fats or oils with an alkali, such as sodium hydroxide or potassium hydroxide, in a process called saponification. This process creates a chemical reaction that transforms the fats and oils into soap.…

Antifertility drugs

Antifertility drugs are medications or substances that are used to prevent or reduce the likelihood of pregnancy. There are several different types of antifertility drugs, including hormonal contraceptives, emergency contraceptives, and male and female sterilization methods. It is important to consult with a healthcare provider to determine the most appropriate form of antifertility drug for…
