Thanks Chris, that's exactly what I'm trying to say. People confuse acceleration with velocity.

That is because the velocity at which the ball is traveling is faster when you throw it harder/higher. The rate of change is constant so the longer time it is airborne is due the additional length of time it takes to decelerate it at the same constant rate…

Imagine a single cylinder 4 stroke engine. The only time that the engine accelerates is during the power stroke. During the power stroke, the acceleration of the flywheel is a function of the force on the piston. During the exhaust, intake, and compression stroke the flywheel is slowing. As long as the acceleration over the power stroke is higher than the deceleration over the following 3 strokes, there will be a net acceleration over the cycle. If you cut the fuel for the next power stroke, the acceleration gets negated. On our engines, this happens very quickly at 6000RPM and there are 4 cylinders, but the physics remain the same.

So imagine there is a plane on a treadmill...

It never ceases to amaze me how people try and prove physics wrong sometimes...

Wait, I think I got this one!

How much does the plane weigh?

Wow,

Can't believe the efforts you guys put in to telling a guy his motor is probably fine. Cracks me up.

I wonder how this thread would have turned out on your Corvette forum

It would have gone off on a tangent the moment the weight of the ***** was mentioned….

That always depends on the viscosity of the Criso…

hahaha -"if I'm running at 2 meters per second straight into a wall, how fast will my ***** continue to accelerate!?"
