Geothermal Energy

What is Geothermal Energy? Geothermal is a Greek word that is formed by the combination of two individual words that are Geo and Thermal. The term ‘geo’ corresponds to earth while ‘thermal’ is associated with heat. Thus, one can define geothermal energy as the heat which exists within the earth. Geothermal Energy is a renewable […]

Ecofriendly Vehicles

What are Eco-friendly Vehicles? Eco-friendly Vehicles are a type of green vehicle also referred to as environmentally friendly vehicles or clean vehicles. Ecofriendly vehicles do not produce that many harmful impacts to the environment that the vehicles with internal combustion engines produce. Basically, eco-friendly vehicles are powered by alternative fuels and are incorporated with advanced […]

Difference Between Planet and Satellite

Planet Vs Satellite Planet and Satellite are the two astronomical bodies that exist in our solar system. One of the significant points of differentiation between the two is that planets can never be made artificially or are not man-made. On the other side, satellites can be of natural or artificial nature. Planet A planet is […]


What is Rheostat? A rheostat is an electronic instrument that is used for the purpose of controlling the electric current which is flowing through a circuit. Thus, it is basically a variable resistor that exhibits controlling action. The name for this instrument was given by an English scientist Sir Charles Wheatstone. Basics of Rheostat In […]


What is Motion? In physics, motion is defined as the variation in the position or orientation of any object or body with respect to time. Each and every motion is defined relative to a frame of reference. In general, motion is of three types translational, rotational, and oscillatory. When motion takes place along a line […]


What is Momentum? The term momentum is associated with moving bodies and is the product of the mass and velocity of a body that is in motion. In general, momentum is represented by p. In physics, momentum is the mass in motion and represent the overall motion that any moving object exhibit. Thus, is given […]

Difference Between Petrol and Diesel Engine

Petrol Vs Diesel Engine Petrol and Diesel Engines are known to be internal combustion engines. The crucial difference between petrol and diesel engine is based on the way the combustion is performed by the two types of engines. People generally consider that petrol and diesel engines are somewhat the same as both of them are […]


What is Mechanics? Mechanics is defined as the oldest branch of physical science that describes the study of the effect produced when a body or object (at rest or in motion) is subjected to force. It is mainly concerned with the prediction of physical phenomena. Basically, mechanics aims to determine and explain the physical behaviour […]

Thermal Conductivity

What is Thermal Conductivity? The word thermal is associated with heat. Thermal conductivity is a property that corresponds to the ability of any material to pass (or conduct) heat through it. Like convention and radiation, it is another method of heat transfer that takes place in various materials. Some general denotions of thermal conductivity are […]

Stress and its Types

What is Stress? Stress is defined as the internal opposition which a body offers when an external force is provided to it per unit cross-sectional area. Stress always acts normal to the plane. Stress is given as force acting on a unit area. And is denoted by σ. σ = F/A SI unit: Nm-2 Dimensional […]
