Gravity is also called gravitation. The universal force of attraction acting between all matter. It is the weakest known force in nature and also thus plays no role in determining the internal properties of matter. It has long reach and universal action and it controls the trajectories of bodies in the solar system and elsewhere […]
Music is an element common to all known cultures around the world. Still, it is beyond an exact definition. We are aware of the fact that music is primarily sound but, what seems curious is that all sounds are not music. It is an arrangement of sounds to generate rhythm, melody or harmony. Physics of […]
It is the class of physical attributes that are mediated by a magnetic field. The magnetic moments of elementary particles and electric currents give rise to a magnetic field and it acts on other currents and magnetic moments. Ferromagnetic materials are strongly attracted by magnetic fields and can be magnetized to become permanent magnets thereby […]
Have you ever wondered why few insects like water striders walk in water? or why do small droplets of rain stick to our window?. The scientific explanation of this phenomenon is associated with the term “Surface Tension”. Surface Tension is the tendency of the surface of a liquid to contract until it reaches the smallest […]
The vibration that propagates as an acoustic wave, through a transmission medium such as a solid,liquid or gas is known as sound. Only acoustic waves that have frequencies in the audio frequency range, that is frequencies lying between about 20 Hz and 20 kHz, elicit an auditory percept in humans. Ultrasound Sound waves are sound […]
The force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other is known as friction. There are different types of friction which includes dry friction, fluid friction, lubricated friction, skin friction, internal friction. The force that opposes the relative lateral motion of two solid surfaces in contact is known as dry friction. […]
The quantitative property transferred to a body or a physical system, recognizable in the performance of work is known as energy. It can be in the form of heat and light. Energy is a conserved quantity that is it can neither be converted nor destroyed. It can only be converted from one form to another and this is known as the law of conservation of energy. The […]
A perplexion remains in the air when it comes to picking out the myths and truths about the life of Nikola Tesla, the visionary who changed the history of humankind with his inventions. Tesla, who lived during the period of Edison and Marconi has his name in history for the pronounced contributions made in the […]
Space is a pretty dark place. Even so, some areas are darker than the others. Nothing is darker than a black hole. Black holes are one of the most fascinating objects in our universe and also the most mysterious one. What is Black hole? A black hole is a region in space that has immense […]
