THE ULTIMATE GUIDE TO WORK, ENERGY AND POWER
Concept of work as a measure of energy transfer The concept of work as a measure of energy transfer is fundamental in physics. In simple terms, work is the energy transferred to or from an object by a force acting…
SIMPLE GUIDANCE FOR YOU IN NEWTON’S LAWS OF MOTION
Newton’s First Law Newton’s First Law, also known as the Law of Inertia, states that an object at rest will remain at rest, and an object in motion will continue to move at a constant velocity in a straight line,…
RECOMBINANT DNA TECHNOLOGY
Recombinant DNA technology, also known as genetic engineering, refers to a set of molecular techniques used to manipulate the genetic material of an organism, typically DNA. The process involves cutting and splicing together pieces of DNA from different sources, such…
CELLULAR SUBSTANCE MOVEMENT
Introduction The movement of substances into and out of cells is essential for maintaining proper cellular function and ensuring the survival of the organism as a whole. There are two main mechanisms by which substances can move across the cell…
BIOLOGICAL FUEL GENERATION
The need for new sources of energy arises from several factors, including the increasing demand for energy, the finite supply of fossil fuels, and the growing concerns about climate change. Firstly, global energy consumption continues to rise due to factors…
CONCEPT OF BIOTECHNOLOGY
Biotechnology is a field of science that involves the application of biological processes, organisms, or systems to develop useful products or technologies for the benefit of society. It encompasses a wide range of disciplines such as genetics, molecular biology, biochemistry,…
ALPHA SCATTERING EXPERIMENT
Rutherford’s alpha scattering experiment, conducted in 1911, was a critical step in the development of the atomic theory. It involved firing alpha particles (helium nuclei) at a thin gold foil and observing their deflection. The experiment was carried out in…
THOMSON AND BOHR’S MODELS
J.J. Thomson’s Experiment J.J. Thomson’s experiment was conducted in the late 19th century to study the nature of the cathode rays produced in a vacuum tube. The vacuum tube consists of a cathode (negatively charged electrode) and an anode (positively…
ENERGY IN PHYSICS
Energy is defined as the ability of a system to perform work. It is a scalar quantity that is associated with objects and systems that have the ability to do work or cause changes in other objects or systems. There…
