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?
both are the unit to measure force but the difference is that newton is SI unit and dyne is C.G.S. unit.
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
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
Whoops, I meant 100,000 dyne. My bad.
