two units for work : ~ first is Joule which is equal to Newton .meter .. ~ second is kilogram .meter square per second square i.e kgm ²/ s ²
the second unit is derived from the first unit Newton .meter Newton = kgm/s ²* and then multiply m .. it will be equal to kgm ²/s².. **
W = Pt This means: Work in Joules (J) = Power in Watts (W) × Time in Seconds (s)
W = F d This means: Work in Joules (J) = Force in Newtons (N) × Distance in Meters (m)
Work in physics is measured in units such as Joules (J) and foot-pounds (ft lb). The joule is the standard SI unit, while the foot-pound is used in the imperial system. Both units illustrate the connection between force and distance in calculating work.
