Static GK decides most of the General Awareness score in SSC exams. The CGL, CHSL and CPO notices describe it in almost the same words: questions on India and its neighbouring countries in History, Culture, Geography, the Economic Scene, General Policy and Scientific Research, and on everyday observation in its scientific aspect. The GD notice adds Sports, General Polity and the Indian Constitution, and the MTS notice lists Social Studies, General Science and Environmental Studies up to the 10th Standard. This page brings together GK24's GK notes and practice questions tagged for all five SSC exams. The notes follow a subject-wise syllabus, one topic per note in English and Hindi: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, Sports, Awards and Honours, Books and Authors, Days and Dates, and Static GK. Each note is written as short facts and tables so that a topic can be revised in one sitting, and each ends with multiple-choice questions and explanations. The level is what changes between exams: read MTS and GD topics at Class 10 depth, CHSL at Class 12 depth, and CGL and CPO at graduate depth, where questions ask for the article number or the year rather than the broad idea. Start with Polity, History and Geography, which fill the most questions in past papers in GK24's reading, then move to the Economy and Science. After each note, solve its questions here and your exam's previous-year questions on its own page.
Which country hosts the global observance of World Tourism Day 2026?
The host country changes from year to year, and the venue of the official observance is one of the facts most often asked about the day.
Read the full explanation →What is the theme of World Tourism Day 2026?
The day falls on 27 September and the theme chosen for this edition asks how digital innovation and artificial intelligence can change the way destinations are planned, promoted, managed and experienced by travellers.
Read the full explanation →Mechanical energy is equal to:
The mechanical energy of a body is the sum of the energy of its motion and the energy of its position.
Read the full explanation →While releasing the arrow from a stretched bow, the Potential Energy of the bow is converted into?
A stretched bow stores elastic potential energy, and when the string is released that store becomes the kinetic energy of the flying arrow.
Read the full explanation →A boy raises a box with a weight of 120 N from a height of 2 m. The work done by him is ________.
Work done against gravity is weight multiplied by height, so 120 × 2 = 240 joules.
Read the full explanation →What is the principle on which brakes work?
Brakes work on friction: a lining is pressed against a moving drum or disc, and the rubbing force slows the wheel down.
Read the full explanation →A wooden block of mass m1 kg accelerates at 10 m/s² when a force of 5 N acts on it. Another block of mass m2 kg accelerates at 20 m/s² when the same force acts on it. If both the blocks are tied together and the same force acts on their combination, the acceleration will be about:
Find each mass from F = ma, add the masses, then divide the same force by the total. The first block gives m1 = 5 ÷ 10 = 0.5 kg and the second gives m2 = 5 ÷ 20 = 0.25 kg.
Read the full explanation →An object with a mass of 22 kg moving with a velocity of 5 m/s possesses kinetic energy of:
Kinetic energy is half m v squared, so half of 22 multiplied by 5 multiplied by 5 gives 275 joules.
Read the full explanation →A body of mass 2 kg is thrown upward with an initial velocity of 20 m/s. After 2 seconds, its kinetic energy will be: (g = 10 m/s²)
The body is thrown up at 20 m/s and gravity takes away 10 m/s of speed every second, so after 2 seconds its speed is zero.
Read the full explanation →Which of the following is a trivalent doping element?
Boron has three electrons in its outermost shell, so it is a trivalent element and is used as a p-type dopant.
Read the full explanation →What is meant by ABS?
ABS stands for anti-lock braking system, a safety device that keeps the wheels from locking during hard braking.
Read the full explanation →How many P-N junction diode(s) is/are required for a full wave rectifier circuit? (Center-Tap)
A centre-tap full wave rectifier needs two p-n junction diodes, one for each half of the input cycle. The secondary winding of the transformer is tapped at its middle, so its two halves give equal voltages of opposite sign.
Read the full explanation →What is the physical state of water at 12°C?
At normal atmospheric pressure water stays liquid between 0 °C and 100 °C, and 12 °C lies inside that range.
Read the full explanation →If the kinetic energy of a body becomes 256 times its initial value, then the new linear momentum will be:
Kinetic energy depends on the square of the momentum, so the momentum grows as the square root of the energy.
Read the full explanation →If a silicon diode is operating in forward bias in a circuit with 12 V supply and 240 Ω resistor, then what will be the voltage drop across the diode?
A silicon diode in forward bias drops about 0.7 volt across itself, whatever the supply voltage is.
Read the full explanation →The essential organs in a flower for reproduction are:
The stamen and the pistil make the male and female gametes, so they are the essential or reproductive organs of a flower.
Read the full explanation →Which of the following metals does NOT react with Oxygen even at a high temperature?
Silver is a noble metal and does not combine with oxygen even when it is heated strongly. Metals react with oxygen according to their place in the reactivity series.
Read the full explanation →Where is the famous temple of Angkor Wat located?
Angkor Wat stands near Siem Reap in Cambodia and is the largest religious monument in the world. It was built in the early twelfth century by King Suryavarman II of the Khmer empire as a temple of Vishnu, and it later became a Buddhist place of worship.
Read the full explanation →A ball is dropped from a height of 10 m. It strikes the ground and rebounds up to a height of 2.5 m. During the collision, the per cent loss in the kinetic energy is:
The ball falls from 10 m but rises back only 2.5 m, so it keeps one quarter of its energy and loses three quarters.
Read the full explanation →Which eminent Hindi writer was chosen for the Vyas Samman 2017 for her work 'Dukham Sukham'?
The Vyas Samman for 2017 went to the Hindi writer Mamta Kalia for her novel 'Dukham Sukham'. The Vyas Samman is given every year by the K.K.
