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.

When forests are cleared, wetlands drained and grasslands ploughed, species lose the space they need, and the fragments that survive are often too small to support large animals or to allow populations to mix and breed.

The day marks the adoption of the text of the Convention on Biological Diversity and is used each year to draw attention to the loss of species and habitats.

Ex-situ conservation means protecting a species away from its natural habitat, and a seed bank does exactly that by storing seeds under controlled temperature and humidity for future use.

Project Tiger was launched to protect the tiger by conserving the habitat it needs, and because the tiger sits at the top of the food chain, saving it protects the whole forest below it.

Among species that still survive in the wild this is the most serious category, given to those facing an extremely high risk of extinction in the immediate future.

The convention was adopted in 1971 in the Iranian city of Ramsar, from which it takes its name, and it provides for the listing of wetlands of international importance and for their wise use by the countries that sign it.

The Wildlife (Protection) Act provides the legal basis for declaring national parks and wildlife sanctuaries, lists protected species in its schedules, and prohibits hunting and trade in the species it covers.

The core zone is legally protected and left undisturbed, with no human activity allowed. The buffer zone around it permits research, education and limited use of resources that does not damage the core.

It spreads across the meeting point of Tamil Nadu, Kerala and Karnataka in the Western Ghats and takes in several well known national parks and sanctuaries within its area.

The Convention has three objectives: the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of the benefits arising from the use of genetic resources.

They are a broken and comparatively dry hill chain and do not meet the twin tests of exceptional endemism and severe threat that define a hotspot.

A region qualifies when it is exceptionally rich in species found nowhere else and has already lost most of its original vegetation.
