If an object is on a level surface and the force tending to cause it to slide is horizontal, the normal force N\, between the object and the surface is just its weight, which is equal to its mass multiplied by the acceleration due to earth's gravity, g. If the object is on a tilted surface such as an inclined plane, the normal force is less, because less of the force of gravity is perpendicular to the face of the plane. Therefore, the normal force, and ultimately the frictional force, is determined using vector analysis, usually via a free body diagram. Depending on the situation, the calculation of the normal force may include forces other than gravity.

he High Court ruled in July 2008 that the News of the World had breached Mosley's privacy. He was awarded £60,000 in damages.

Arguably the most famous journalist on the paper in recent years was undercover specialist Mazher Mahmood.

His exposes - often carried out using his disguise as the "Fake Sheikh" - targeted everyone from the Countess of Wessex to former England football manager Sven-Goran Eriksson. The News of the World also claims he has brought about the conviction of more than 250 criminals.

In August 2010, posing once again as the "Fake Sheikh" he exposed a group of Pakistani cricketers, accused of corruption.
