Motion

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 […]

Momentum

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 […]

Mechanics

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 […]

Diffraction of Light

What is Diffraction of light? Diffraction of light is an act defined as the bending of light rays across the edges of a surface. Diffraction is regarded as a universal phenomenon possessed by waves. A major question arises just by reading out the definition of diffraction that where it is observed and how this happens. […]

Components of Electric Circuit

The elements or components of electric circuits are the ones that form the circuit in order to provide accurate circuit operation. The fundamental components of electric circuits are resistor, inductor, and capacitor. What is an Electric Circuit? An electric circuit is defined as a closed-loop within which the flow of electric current takes place in […]

Electromotive Force

What is Electromotive Force? Electromotive Force is an electrical phenomenon which results in the generation of electric potential (voltage). Electrochemical cells or changing magnetic fields generally give rise to electromotive force. It is regarded as the fundamental property of an energy source that permits the motion of charges within the circuit. Sources of Electromotive Force […]

Energy Conversion

What is Energy Conversion? The term conversion is used to represent change or transformation. In correspondence to energy, the term conversion defines the transformation or change of energy from one specific form to another. Thus, changing one type of energy to a different type is known as Energy Conversion. It is sometimes referred to as […]
