5.Work and power formula
Symbol description and unit
(1) work
A=F*S 〔kgf・m〕
A=
F: The power to work 〔kgf〕
S: Moving distance 〔m〕
(2-1) power
P=A/t 〔kgf・m/s]
P=
A: work〔kgf・m〕
t: Time to work 〔s〕
(2-2)power
P=F*S/t 〔kgf・m/s〕
P=
F: The power to work 〔kgf〕
S:Moving distance 〔m〕
t: Time to work 〔s〕
(2-3) power
P=F*ν 〔kgf・m/s]
P=
1kW=102kgf・m/s
P
kW
=P/102 〔kW]
P
kW
=
F: The power to work〔kgf〕
ν:Force F speed 〔m/s]
(3)Conversion of power unit
1kgf・m/s=9.8J/s=9.8W
1W=0.102kgf・m/s=1J/s
1kW=102kgf・m/s≒1.36S
1PS=75kgf・m=0.736kW
