On a velocity-time graph the height of the curve is velocity and the base is time, so the area enclosed is velocity multiplied by time, which is displacement.

The three equations of uniformly accelerated motion are v equals u plus at, s equals ut plus half of a t squared, and v squared equals u squared plus twice a s, where u is the initial velocity, v the final velocity, a the acceleration, t the time and s…

While the bus is moving, the passenger's whole body moves with it. When the brakes are applied, the feet stop along with the floor of the bus, but the upper body tends to keep moving forward at the same speed, and the passenger is thrown forward.

Momentum is the product of mass and velocity, so its unit is the unit of mass multiplied by the unit of velocity, that is kilogram multiplied by metre per second.

Before firing, the gun and the bullet are at rest, so the total momentum of the system is zero.

It states that the rate of change of momentum of a body is proportional to the applied force and takes place in the direction of the force.

It is the shortest distance from the starting point to the finishing point together with the direction of that straight line, so it has both magnitude and direction and is therefore a vector.

The first law states that a body continues in its state of rest or of uniform motion in a straight line unless an unbalanced external force acts on it, which is exactly the property called inertia.

Article 51A(f) actually asks citizens "to value and preserve the rich heritage of our composite culture". The word matters: India's culture is described as composite, a blend of many traditions, languages and faiths, not a single unitary culture.

Voting is not among the eleven Fundamental Duties in Article 51A. The right to vote comes from Article 326, which provides for elections on the basis of adult suffrage, and from the Representation of the People Act, 1951.

In 1999 the Committee on the Fundamental Duties of Citizens, headed by Justice J.S. Verma, a former Chief Justice of India, looked at how the duties could be made operational.

The Supreme Court has held that when a court tests whether a law is constitutional, and finds that the law gives effect to a Fundamental Duty, it may treat the law as "reasonable" under Article 14 or Article 19 and uphold it.

Teaching people to turn kitchen waste into compost for a park reduces waste and enriches the soil, which is exactly what Article 51A(g) asks for: to protect and improve the natural environment, including forests, lakes, rivers and wildlife, and to have compassion for living creatures.

The tenth Fundamental Duty is clause (j) of Article 51A, which continues: "so that the nation constantly rises to higher levels of endeavour and achievement".

That is the duty in Article 51A(i). It asks citizens not to damage buses, trains, roads, government buildings and other public property, and to reject violence, for example during protests.

Article 51A(h) asks every citizen "to develop the scientific temper, humanism and the spirit of inquiry and reform". It means questioning superstition, looking for evidence before believing a claim, and being open to change.

The very first Fundamental Duty asks every citizen to abide by the Constitution and respect its ideals and institutions, the National Flag and the National Anthem.

The 86th Amendment Act, 2002 inserted clause (k) in Article 51A: "who is a parent or guardian to provide opportunities for education to his child or, as the case may be, ward between the age of six and fourteen years." The same amendment made free and compulsory education for children…

The 42nd Amendment Act, 1976 added ten Fundamental Duties in Article 51A, clauses (a) to (j).

The idea of writing citizens' duties into the Constitution was taken from the Constitution of the former Soviet Union, which listed duties alongside rights.
