I never ever thought, that this discussion will develop so much:smile: I asked super stupid question showing that my knowledge of physics is misunderstood by myself. But I analized all post and I drew conclusions which i wrote at post #61

I admit, I was wrong, I didn't understand the basics. That's why I came here to learn and understand more of basic physics. I have read all posts and what I've learned (I think) is this: Force causes the acceleration of a mass because F = m*a Engine power generate a force which accelerate a...

What is PF ? And what proffesional scientific literature You suggest me to learn about power, torque force etc?

if it is true, it is ruining my worldview. I start to learn some physics just for fun some time ago because I was curious how torque and power works. And those guys looking trustable for me... And now I feel crushed...

How is that possible that those 2 enginers are wrong?

This is Jason Fenske who is mechanical engineer said: at 2:10 that "power is what gives you speed, what gives gives you acceleration" and at 7:05 "how fast will a car be able to accelerate, what will its top speed be - that comes down to power" This is John Cadogan who is also mechanical...

This is start to be more confused than it was:) So torque is moment of force, a parameter that is directly related to the instantaneous acceleration at all times So why we even calculate power? If power doesn't generate a force which pushing car forward? Please don't tell me that average 100Nm...

Torque from the engine is limited by revs. We can use CVT transmision to accelerate forever but there we hit a point where all forces (friction , air resistance, etc) will stop car and that's the car top speed. Is that Correct? So let's go back to jet plane where we can also use 2nd...

So " always power you feel" is wrong. It should be like this: Engine power generate a force which accelerate (and force you feel) a car because F = ma. More power = more force pushing car forward. Is that correct?

At 20:56 this guy talk about what we feel when we accelerate a car. He said that power cause acceleration not moment of force (torque)... Goshh I got so little brain to understand this ...:)

So F = ma works in jet engine but why we don't use it at car engine? - and we combine "ma with distance over time" to calculate power ?

As we know, POWER is what accelerate a car, FORCE itself doesn't accelerate a car, if FORCE cousing movement it change into work, and work over time = POWER. The FORCE from jet engine pushes a plane forward. But as we know (or I'am wrong) FORCE don't push enything, only POWER couses...

Thank You Guys! I will analyze those informations for better understanding this principals.

Don't understand - can You put more information here

So, dynamic torque = work
