Centripetal force is related to angular velocity in the following manner.
F = m.w2r
where
F = Centripetal force [=] N
w = angular velocity [=] rad/s
r = radius of rotation [=] m
RPM is denoted for Round Per Minute and is the rate of revolution.
RPM x 60 sec/min x 2pi rad/sec = w
Centripetal force is then proportion to RPM2
Most cars are anywhere between 750-800 rpms
mass air flow sensor
about 12, 13,000 RPMS.
lower rpms use less gas higher rpms have more power
The Rpms change because the added resistance to the engine is requiring more force but the force is still being applied
If you have an engine that idles at 6000 rpms, you need to have it checked - immediately. Around 750 rpms would be normal.
The word "centrificel" is not recognised. Please check what it is you want, find its correct spelling and resubmit the question.
It is, Horsepower = Torque x RPM, but Torque is not constant across the rev range of an engine. For gasoline engines, there is generally very little torque at low rpms, generally flat torque across the middle rpms, and then a drop off as the engine starts spinning too fast for complete combustion. Electric engines, on the other hand, start off with maximum torque and decrease with higher engine speed. So, the short answer to your question is that it's a direct relationship between horsepower and torque, but the variation in the torque curve across the rpm range makes the resultant horsepower curve vary too. (If your question was really why does torque vary with rpm, simply stated it's because engines have varying efficiencies at different speeds.)

600 to 1000 revolutions per minute (RPMs) is the typical average for idle.
in relationship to engine rpms a ratio of something like 3.08 would have less acceleration and lower highway rpms compared to 4.11s. the 4.11 ratio would give you better acceleration and less top speed and lower gas mileage at highway speed
There could be any number of reasons but it could be the idle is set too low. The idle is the rpms that your engine runs at just sitting there without you stepping on the gas. It should be somewhere between 800 and 1000 rpms.
between 500/750 depends on where the idle screw is set
