This is the Hidden Killers podcast with Tony Brewski and continuing coverage of the case against Karen Reed.

So, so I just want to get the principles.

So Newton's second, law, force equals mass, time, celebration, and force is oftentimes what you're trying to calculate in a course calculation, correct?

Calculate or major, yes.

And Newton's first law is the law of generally inertia, an object at rest tends to stay at rest,

object of motion, tends to stay in motion. We're not talking about that.

The course we're talking about just's just set a law, correct?

You asked me two questions.

Newton's first law is generally, as you said,

it could be at rest or at constant velocity, but yes.

And that Newton's second law is generally just a mathematical calculation, correct?

Yes.

So what I'd like to do is to turn to page 11 of your report.

And on page 11, you discussed the force calculation in conjunction with the part of your report

where you discuss your experiment where you dropped a test dummy backwards, correct?

Correct.

You determined that a fall of 69 inches at that fall,

Mr. O'Keefe's head would have accelerated with 458 G's of force? That's what we actually measured

in the test? And can you tell the jury what is meant by G's? So G's is a measure of acceleration.

If you take, use the acceler is measured in feet per second squared.

If you divide it by 1G, which is 32.174 feet per second squared, that gives it to you in

G's.
