Energy from fossil fuels refers to the energy obtained through the combustion or burning of fossil fuels, such as coal, oil, and natural gas. Fossil fuels have been formed over millions of years from the remains of ancient plants and organisms. They are considered non-renewable resources because their formation takes an extremely long time compared …
Energy is a fundamental concept in physics that describes the ability of a system to do work. It comes in many forms like kinetic energy, potential energy, thermal energy, electrical energy, etc. Two of the most common forms of energy are kinetic energy and potential energy. Kinetic Energy Kinetic energy is the energy of motion. …
History of Television Television has come a long way since its humble beginnings. From the grainy black and white screens to the vibrant high-definition displays of today, television has evolved to become a cornerstone of entertainment and information in our lives. In this article, we will take a journey through the fascinating history of television, …
What is the Mass of an Object? Mass is a fundamental property of matter that describes the amount of matter in an object. It is a scalar quantity, meaning it has only magnitude and no direction. Mass is usually measured in kilograms (kg) or grams (g). In contrast, weight is a vector quantity, as it …
Force inside the nucleus Inside the tiny world of the atomic nucleus, there are powerful forces at work. These forces hold the nucleus together and control how its particles behave. They are like invisible hands that shape the nucleus’s structure. By studying these forces, we can begin to understand the amazing world that exists deep …
In the world of physics, waves play a crucial role in describing how energy travels through space. One type of wave that we encounter in our everyday lives is the longitudinal wave. From sound waves to seismic waves, understanding the nature of longitudinal waves is essential. What are Longitudinal Waves? Longitudinal waves are a type …
Mechanical waves are waves that need a medium to travel through. This medium can be a solid, liquid, or gas. Mechanical waves happen when particles in this medium vibrate. These vibrations move from one particle to the next, and that’s how the wave moves through the medium. Speed of a Mechanical Wave By multiplying the …
The concept of frequency is crucial in understanding the behavior of vibrating systems. Whether it’s a pendulum swinging back and forth, a guitar string vibrating, or an electron oscillating, the frequency of oscillation determines the rate at which these systems move. In this article, we will study the details of frequency, explore its calculation formula, …
The formula for the time period (T) of a simple pendulum is: T = 2π √(L/g) Where: T represents the time period of the pendulum, measured in seconds (s). π (pi) is a mathematical constant approximately equal to 3.14159. L represents the length of the pendulum, measured in meters (m). g represents the acceleration due …
A simple pendulum is a weight attached to a pivot, allowing it to swing freely. When it’s pushed aside from its resting position, gravity pulls it back, creating a restoring force. Once released, this force causes the weight to move back and forth in a smooth, regular motion known as simple harmonic motion. Time Period …
