# Thrust and Pressure

When a book is kept on a table its weight acts downwards and presses on the surface of contact of the table. This pressing force acting over the entire area of the surface is called thrust. Thrust is the total force acting perpendicular to the surface. The unit of thrust is Newton.

The force acting (thrust) per unit area is called pressure. The unit of pressure in the S.I. system is Newton/m2.
