what is relation between the newton and dyne ?
1 newton = 1 kg m/s2
and 1 dyne = 1 g cm/s2
Now, 1 Kg=1000 g and also 1 m = 100 cm.
So, 1 newton = 1000 g 100 cm/s2
1 newton = 105 g cm / s2
1 newton = 105 dyne.
Dyne is CGS (centimeter-gram-second) form of Newton (which is SI unit form). Please do cross check this information.
1 Newton = 1000 dyne
Just think of it this was, 1 Kilogram = 1000 gram, makes sense now right?
F = 1N
m = 1kg
a = 1 ms-2
F = ma
Substituing the values in the eqnwe get
1N = 1kg x 1 ms-2
since 1kg = 1000g , 1m = 100 cm
1N = 1000 g x 100 cm-2
1N = 105 g cms-2
since 1 dyn = 1 g cm-2
1 N = 105dyn
relation between newton and dyne
we know, 1 newton = 1 kg m/s ...... (1)
now 1 kg = 1000g = 103g
1 m = 100 cm = 102cm
put these values in eqn.(1), we get
therefore 1 newton = 103gX 102cm /s2
= 105g cm/s2
but 1 g cm/s2= 1 dyne
therefore1 newton = 10 5 dyne
Whoops, I meant 100,000 dyne. My bad.
both are the unit to measure force but the difference is that newton is SI unit and dyne is C.G.S. unit.
