What Do You Mean By Thrust And Pressure ThrustThe force acting normally on surface is called 'thrust'. This is a vector quantity. It is measured in newton (N).PressureThe thrust on an unit area of a surface is called 'pressure'. Unit: The SI unit of pressure is newton per meter square or N/m2, other units of pressure are pascal and bar. One … [Read more...] about How Pressure is Related to Force and Area

What is Atmospheric Pressure
What is Atmospheric Pressure Scientists discovered atmospheric pressure in the seventeenth century. This discovery uncovered an interesting fact that air actually has weight! The weight of the atmosphere presses down on the Earth’s surface and creates a pressure on it. The pressure at any point exerted by the weight of the air above it is called atmospheric … [Read more...] about What is Atmospheric Pressure
Understanding Pressure Using Pascal’s Principle
Understanding Pressure Using Pascal’s Principle A boy applies pressure on a tube of toothpaste. The pressure applied to the tube is transmitted throughout the toothpaste and forces it out of the opening of the tube.Figure shows a boy holding a plastic bag with holes. When he squeezes the plastic bag, the water squirts from all the holes in all directions. … [Read more...] about Understanding Pressure Using Pascal’s Principle
Understanding Gas Pressure
Understanding Gas PressureFigure shows a boy pressing the front tyre of his bicycle. (a) When he presses the tyre with his thumb, he feels an opposing force acting on his thumb. (b) The force is due to the air pressure in the tyre. (c) The air pressure is due to the collisions of air molecules in the tyre against the wall of the tyre. Figure shows air molecules in … [Read more...] about Understanding Gas Pressure
Applications of Pressure in Daily Life
Applications of Pressure in Daily Life Some of the applications of pressure are given below.The area of the edge of a knife’s blade is extremely small. This creates a pressure high enough for the blade to cut through a material. Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its … [Read more...] about Applications of Pressure in Daily Life
