Given: 2 units
To Prove: kgm/s = N.s and represent the same quantity.
quantity =?
Solution:
N - Newton is the SI unit used for force.
Formulas:-
The Formula for force = mass(m) × acceleration(a)
The formula for acceleration = velocity(v) × time(t)
The formula for velocity = displacement (s)/time(t)
∴ acceleration (a) = s/t²
S.I unit for the quantities are as follows:-
mass - m = kilogram - kg
Distance/Displacement- s = meter - m
time - t = seconds - s
Force - F = Newton - N
Hence Force = m × s/t²
F =
F = kg × m/s²
1 Newton = 1 kgms⁻²
Multiplying time on both sides:-
1 N.s = 1
1 N.s = 1 kgms⁻¹
Hence proved.
The Quantity that the above units represent is momentum "p".
p = mv (m - mass, v - velocity) or F × t
unit = kgm/s
