The Richter scale, devised by Charles F. Richter in 1935, expresses the energy released at the source of the shock.

The focus, also called the hypocentre, is the point below the surface at which the strained rock ruptures and releases its stored elastic energy as seismic waves.

Secondary or S waves are transverse, so the particles of the medium move at right angles to the direction of travel.

In orbit the gravitational pull of the earth is the very force that keeps the craft curving around the planet, and the craft, the astronaut and everything inside accelerate towards the earth at the same rate.

The pressure at a point inside a liquid equals the depth multiplied by the density of the liquid and by the acceleration due to gravity.

In 1798 Cavendish used a delicate torsion balance to measure the extremely small attraction between lead spheres in a laboratory and from it obtained a value of G, about 6.674 times ten to the power minus eleven newton metre squared per kilogram squared.

A mercury barometer balances the pressure of the atmosphere against a column of mercury, which stands about 76 centimetres high at sea level.

Weight equals mass times the acceleration due to gravity, and the acceleration due to gravity on the moon is about one-sixth of its value on the earth because the moon has a much smaller mass and a smaller radius.

It states that a body immersed wholly or partly in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced, so the apparent loss in weight of the body equals the weight of the displaced fluid.

Pascal's law states that pressure applied to an enclosed fluid is transmitted undiminished in every direction to all parts of the fluid and to the walls of the container.

Escape velocity is the minimum speed a body must be given so that it leaves the gravitational pull of the planet and never returns.

The earth is flattened at the poles, so the distance from the centre is least there, and since g varies inversely as the square of that distance, g is largest at the poles.

Pressure is thrust per unit area, so its unit is one newton per square metre, and this unit is named the pascal after Blaise Pascal.

The philosopher and teacher Dr S. Radhakrishnan was India's first Vice-President, from 1952 to 1962, serving two full terms. He then became the second President of India (1962–67).

Under Article 67(b), the Vice-President can be removed by a resolution of the Rajya Sabha passed by a majority of all its then members, an "effective majority", and agreed to by the Lok Sabha by a simple majority.

It provides that the Vice-President shall be elected by the members of an electoral college consisting of the members of both Houses of Parliament, elected and nominated alike, by proportional representation through the single transferable vote and by secret ballot.

Article 64 makes the Vice-President the ex officio Chairman of the Council of States, that is, the Rajya Sabha. "Ex officio" means by virtue of the office: nobody elects the Chairman separately.

Droupadi Murmu was elected President in July 2022, defeating Yashwant Sinha, and took the oath on 25 July 2022, succeeding Ram Nath Kovind, the 14th President.

The Constitution does not fix any time limit within which the President must give or withhold assent to an ordinary bill.

Article 143 gives the Supreme Court its advisory jurisdiction: when a question of law or fact of public importance has arisen or is likely to arise, the President may refer it to the Court for its opinion.
