A kg-m is the unit of the moment of inertia per unit length on this line. Consider a car moving on a road with streetlamps. The faster the streetlamps go by, the more momentum the car has. The momentum per unit freqency of the car has units kg-m. A …

Jan 11, 2019 · The non SI unit is often written as 1 kg-m and is equal to 9.8 N m. In such a case the 1 kg refers to the unit 1 kg force which is the weight of one kilogram. Another unit is the Imperial (and US) unit the pound-foot which is equal to approximately 1.36 N m. Here the unit of force is the pound force.

Feb 17, 2022 · 1 N = 1 kg · m/s². this can be treated just like a mathematical equation N = kg · m/s², thus introducing a new "variable" named N, and we know it to be the the "variable" kg, multiplied by m, divided by the square of s. If we look at the equation on force, mass and acceleration. F = m · a. with values e.g. m = 1000 kg. a = 2 m/s²

Mar 18, 2024 · Derived units, like a Newton, are simply convenient shorthand for expression combinations of those three scales (e.g., ${\rm 1\ N}=1\ {\rm kg\cdot m \cdot s^{-2}}$). However, even though we have defined a numerical value for all physical quantities, the actual numerical value is arbitrary , because it depends on our arbitrary choice of ...

Jun 3, 2020 · N/kg is equivalent to m/s $^2$ so it is fine to use as it as a unit of acceleration. If you have an acceleration of 10 N/kg, that means the net force on you is 10 N for every individual kg of your mass. In fact, I often use this convention with my students learning gravitational field/acceleration.

You will perhaps gather from this that 1 N/kg = 1 m/s$^2$ as force = mass $\times$ acceleration so $\dfrac {\text{force}}{\text{mass}} = \text{acceleration}$ which can cause further confusion because you could say that the gravitation field strength on the Earth is 9.8 m/s$^2$ and be using the correct units.

Apr 23, 2015 · The SI units for electromagnetism are based on the ampere, which is. that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to $2\times10^{-7}$ newton per meter of length.

Mar 28, 2022 · $${\rm kg\cdot m/s^2\times m = kg\frac{m^2}{s^2}=kg \Big(\frac{m}{s}\Big)^2}$$ which agrees with kinetic energy being $\frac 1 2 m v^2$. Perhaps $\hbar$ 's most famous role is relating frequency and energy: $$ E = \hbar\omega $$ or $$ \hbar = \frac E {\omega}$$

Dec 22, 2017 · About this question,I found this from the Wikipedia:nuclear fission produces neutrons with a mean energy of 2 MeV (200 TJ/kg, i.e. 20,000 km/s), which qualifies as "fast". For my question, I only knew a few detail that converting Electron volt to Velocity unit,and electron volt is closely related with energy density, but I don' know the ...
