In this video I want to clarify two ideas that we talk about on a regular basis but are really kind of muddled dumped in our popular language and these are the ideas of mass mass and weight and first I'll tell you what they are and then we'll talk about how they are muddled up so mass is literally there's a couple of ways to view mass one way to view mass is and this is not a technicalIf you're behind a web filter, please make sure that the domains *kastaticorg and *kasandboxorg are unblockedMass is a scalar, given in (kilo)gram as SI/CGS unit and never changes its value alone by changing the location 1 kilogram is 1 kilogram on earth, in 10 000 km over earth, on the Jupiter or Sun or in a space station in weightlessness Weight is, as you already mentioned, a vector and given in Newton/dyn as SI/CGS unit It is the force a given

W=mg si units-Important The slug is the base unit for mass in the English system, but the more common unit for mass is the Pound Mass (lbm)Under standard Earth gravity, 1 lbm weighs 1 lbf and therefore the term "pound" is usually used for both mass and weight in the English system MASS Conversions 1 lbm = * kg (exact conversion) 1 kg = lbm 1 slug = lbmF = m * a F = kg * 3 m/s 2 F = 60 N Newtons are a derived unit, equal to 1 kgm/s²
