Resolving Vectors

A quantity with magnitude and direction is defined as a vector quantity. The weight of an object, velocity, and acceleration of a vehicle and the force acting on a bridge are some examples of vector quantity.

Scalars & Vectors

Consider a car that is travelling from city A to city B. The distance travelled by the car can be calculated by multiplying the average speed of the car and the time taken.

Stable & Unstable Nuclei

An atom contains an equal number of positively charged protons and negatively charged electrons and their charges balance. However, the nucleus contains positively charged protons, which are closely packed together in a very small volume.

Stress & Strain

Ever wondered why, when iron rod can withstand more load, things made of glass or wood breaks easily? The answer lies in behaviour of materials to external loading. This article discusses some of the important properties of the materials that are used to study the effect of when an external load is applied to materials.

Superposition of Waves

If two or more waves collide, they are said to interfere. Interference is a property of waves. In this article, properties of the resultant waves created in interference is explained.

Wave-Particle Duality

Light waves can behave like particles (photons) and waves. This phenomena is called the wave-particle nature of light or wave-particle duality. In this article, how a light wave behaves like a particle and a wave are explained.

Young’s Modulus

Young’s modulus is a numerical constant, named after the 18th-century English physician and physicist Thomas Young. Young’s modulus is a measure of the ability of a material to withstand changes in length under lengthwise tension or compression.
