NEET was initially proposed to take place from 2012 onwards. [6] However, for several reasons, the CBSE and Medical Council of India deferred NEET by a year. [7] The test was announced by the Government of India and was held for the first time on 5 May 2013 across India for students seeking admission for both undergraduate and postgraduate ...
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
The National Testing Agency (NTA), entrusted with organizing NEET (UG) 2024, has taken significant steps to address such challenges. These measures include deploying advanced security technologies, increasing CCTV coverage, and enforcing stricter protocols for invigilators to ensure a fair and transparent examination environment.
A common misconception occurs between centre of mass and centre of gravity.They are defined in similar ways but are not exactly the same quantity. Centre of mass is the mathematical description of placing all the mass in the region considered to one position, centre of gravity is a real physical quantity, the point of a body where the gravitational force acts.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
In physics, Gauss's law for gravity, also known as Gauss's flux theorem for gravity, is a law of physics that is equivalent to Newton's law of universal gravitation. It is named after Carl Friedrich Gauss. It states that the flux (surface integral) of the gravitational field over any closed surface is proportional to the mass enclosed. Gauss's ...
Physics Wallah, or "PW", was founded in 2016 as a YouTube channel hosted by Alakh Pandey, an educator hailing from Prayagraj, Uttar Pradesh.The channel was initially focused on teaching the physics curriculum for the Joint Entrance Examinations (JEE), a popular entrance examination in India. [2]
The first test of Newton's law of gravitation between masses in the laboratory was the Cavendish experiment conducted by the British scientist Henry Cavendish in 1798. [5] It took place 111 years after the publication of Newton's Principia and approximately 71 years after his death.
