How about a real world example for us. So 2 kg @ 1 meter out accelerating @ 1 G. How many kw does it take?SchmidtMotorWorks wrote: ↑Tue Mar 14, 2023 10:50 amEnergy is sufficient to describe the consequence of reduced mass to acceleration.digger wrote: ↑Tue Mar 14, 2023 4:47 amif youre talling about acceleration there is time factor involved hence energy and time are where the power comes fromSchmidtMotorWorks wrote: ↑Mon Mar 13, 2023 11:25 pm
Since we are talking about accelerating a mass, Energy seems like the right way to define it.
If someone says, "for a given energy, a lesser mass will accelerate faster than a greater mass" the appropriate reply would be "duh".
the reality is if on a transient power run of chassis dyno increasing rotational mass results in less power at the wheels, the engine is making the same power but a portion is being consumed in accelerating mass.
if you have no frictional losses and the gearing is 1:1 the flywheel torque will still NOT equal wheel torque as it is not in static equilibrium. A sum of moments will show you this
