thanks again krab. I thought(key word) that slugs was a unit of momentum.? Well, since I'm not trained in Physics, let me guess, momentum is a measure of mass? M*V? cookiemonster, isn't centripetal the counter force of centrifugal? So to speak anyway. I realize it's probably not the...

thanks all. HallsofIvy, that was 200 grams, but I got your meaning. krab, thanks for the refresher. It's been a while. I use cross multiplication(term when I attended school or ratio) all the time. Me thinks the formula is not correct, or better yet my math skills have deteriorated...

no physicist here, but distortion thru refraction seems to be culprit.

thanks for info. I, being from the USA, prefer pounds,psi, or whatever the units would be expressed as. Slugs? :redface:

I have a simple math problem. I know the basic formula, but am too far removed from math lessons(50 years of age) to figure it out. I know you require like units to derive an answer. A 200 gram object is rotated around a 4' radius at 100 mph. What is the centrifugal force? I know(at least...

Thanks Hurkyl. Reflection. Why didn't I think of that? Please don't answer that.

Thanks Russ for your reply. I like the billiard ball analogy. It made me think, then things got fuzzy. Let me ask a simple question. If a block of steel cut to a 20° angle on the leading edge was propelled into a ball along a straight line, what angle would the ball take off in? Would...

vector force? Hi all. I'm in search of a simple answer to a simple question that has become seemingly impossible for me to find. I'm not schooled in Physics. I can cypher fairly well, but this doesn't really(I think)require cyphering. It's a question of golf club golf ball collision...
