![]() You might use the dyne if you are working with very small objects. There are two other units of force in Physics however, they are not as commonly used as the SI unit of force Newton.ĭyne: A dyne is a force required to give a mass of 1 gram (1 g) an acceleration of 1 centimetre per second squared (1 cm/s²). Inshort,displacement is distance in vector form(same as how velocity is speed in vector form), So displacement is measured in metres. NOTE: Displacement is the shortest distance from the initial to the final point. = P/ t įorce= mass*velocity / time - (replacing terms with their respective units) We also know that momentum (P) is the product of mass(m) and velocity(v). ![]() Therefore, the FPS unit of force is lb-ft/s², which is called poundal or pdl.įrom Newton’s Second Law of motion, force is equal to the rate of change in momentum (P). In the FPS system of units, the unit of mass is pound or lb, and the unit of acceleration is feet per second squared or ft/s². Therefore, the CGS unit of force is g cm/s², which is called dyne or Dyn. In the CGS system of units, the unit of mass is gram or g, and the unit of acceleration is cm/s². Therefore, the unit of force is kg m/s², which is what we refer to as Newton or N. In both the SI system (the International System of Units) and in the MKS system, the unit of mass is kilogram, abbreviated as kg, and the unit of acceleration is m/s².
