Question

Wypisz i rozpisz 5 pochodnych jednostek. Według tych przykładów

F=m*a
1N= [1kg*m/s^2]
[a]= [m/s^2]
[1J]= 1N*1m

W=F*s
[1J]= kg*m/s^2 * m
[1J]= kg*m^2/s^2

Answer 1

P=W/t

[W]=J=1kg*m^2/s^2

[t]=s

[1W]=1J/1s

 

V=s/t

[s]=m

[t]=s

[V]=m/s

 

E=1/2*m*V^2

[m]=kg

[V]=m/2

[1J]=kg*m^2/s^2

 

E=mgh

[m]=g

[g]=m/s^2

[h]=m

[1J]=kg*(m/s^2)*m=kg*m^2/s^2

 

F=1/T

[T]=1s

[Hz]=1/s

 

W=U*I*t

[U]=1V

[J]=1A

[t]=1s

[1J]=V*A*s
