Let's see you prove your credibility.

Pics. Or it didn't happen.


See what I did there? Physicist.

It's hanging on the shop wall at the dealership currently. Ask me anything you'd like though. I mean, I could show you all my individual certifications if you'd like.

You're saying that velocity kills, when it does not. It's the force from a sudden stop that kills, the sudden deceleration. What I am saying is not merely "intern's nonsense", I think you've got your positions in this dilemma mixed up.

P.S.
How do fast attack/intercept jets go the speed I just described without colliding with anything? They seem to do it just fine without collision.

There you go again, assuming we're on planet earth. Didn't you say something about making assumptions? I swear I heard the word dangerous thrown around in there somewhere too.

Velocity and acceleration are two separate entities. You're literally disproving all of the credit you've earned so far. You're not right, and you've actually started down the path of proving yourself wrong.

I'm an ASE certified master mechanic; you, as it turns out, are not. Besides, we never moved past highschool level physics in this discussion. You can conclude all you want, which in this case concludes you admitting you're not in your area of expertise anymore.

You have not studied me, you've merely communicated with me for but a brief few comments. Acting like adding a Z axis magically makes you right is not correct. The fact still remains, speed does not kill. Acceleration does however, and it is not direction dependent. Velocity however, is, but it is not the acting force.

Not at all. Let's sidestep to my original comment where I stated the difference between velocity and acceleration. Acceleration is what kills you, velocity does not. Accelerating too fast, will in fact kill you. But simply going a thousand miles per hour will not kill you.

You've got the 25-60ms area in an airbag's timeline of operation described spot on. Now fill in the 0-25ms and 60-1,000ms sections.

No, in this instance my science still stands. A person does not have to be in a vehicle to prove this. Now you're the one assuming the person is in a car.

Really? We're talking about photos of Jeremy Clarkson, host of a show explicitly about cars. Do I really need to explain any more? Now you're just trying to bait me into a logic trap.

Gravity pays little to no part in stopping a car, assuming it's on a flat surface. The drag you are talking about is better represented by the friction caused by the contact surfaces between the car and road, wheel bearings, drivetrain components, and more importantly since this is the major acting force of friction on a car: the car as a whole pushing itself through the air; aka aerodynamic forces. You really don't take drag(you do occasionally, because racecar, but not for a daily driver) and gravity into consideration unless you're talking about objects moving in not only an X and Y axis, but also a Z axis. Your point doesn't even stand up to proven science. You're spouting pseudo science.

What you just said doesn't even make sense.

again, i wasn't speaking of the strict definition of speed i was speaking in laymen's terms; i've had a semester and a half of college physics now....believe me, i understand your point and the point anon was trying to make...

acceleration is the SOLE cause of force? tell me, what is the force produced by a massless photon?

...finally someone gets it...

I know how you feel. My left eye is ridiculously near sighted. People used to jokingly take my glasses off and put them on, then freak out when they realized they were real, and that my prescription was so strong it gave them instant headaches ha.
