Category: 1. Force And Pressure

The Force can be measured using a spring balance. The SI unit of force is Newton(N). Common symbols: F→, F SI unit: Newton In SI base units: kg·m/s2 Other units: dyne, poundal, pound-force, kip, kilo pond Derivations from other quantities:  F = m a Dimension: LMT-2

The force, applied on a unit area of a surface is known as pressure Pressure=force/areaonwhichitactsPressure=force/areaonwhichitacts. If the area is smaller, then the pressure on a surface would be greater; e.g. this is the reason that the area of one end of a nail is pointed toexertsufficientpressuretoexertsufficientpressure and other end is bigger asshownintheimagegivenbelowasshownintheimagegivenbelow. This envelop of air is known as the atmosphere that… Continue reading Pressure

When an object is either pushed or a pulled is known as a force. Motion, generated in an object, is because of an action of a force. The applied force makes the table move in a given direction. The strength of a force is commonly expressed by the magnitude. Force also has direction; likewise, if… Continue reading Introduction
