It would help me if you could read this and tell me if you agree with it or have issues with it.
If one of my students wrote it, I'd say that they demonstrate a pretty good understanding of the ideas, but I'd suggest they tighten up some of the expression.
For example
Quote:
If you are in an automobile when the brakes are abruptly applied, then you will feel pushed toward the front of the car. You may actually have to extend you arms to prevent yourself from going forward toward the dashboard. However, there is really no force pushing you forward. The car, since it is slowing down, is an accelerating, or non-inertial, frame of reference, and the law of inertia no longer holds if we use this non-inertial frame to judge your motion.
might become

If you are in an automobile when the brakes are abruptly applied, then it is easy to believe that you are being pushed toward the front of the car. You may actually have to extend you arms to save yourself from a collision with the dashboard. A camera mounted inside the car would certainly show you accelerating forward. However, when viewed from outside the car there is no sign of any force pushing you forward. The difference in perception is that the car, since it is slowing down, is an accelerating, or non-inertial, frame of reference, and the law of inertia no longer holds if we use this non-inertial frame to judge your motion.
I could go a bit further in modifying the text, but you get the idea. Basically it is fine, but some of the wording could mislead somebody who does not already understand the subject. I probably would not use the "law of inertia" in my explanation, but would not tell a student to remove it.

My post above was edited by someone other than myself. It completely changed the nuance and meaning.
NO ONE has the moral right to change the meaning of my posts. Because it is your website you have the right to ban me or delete my posts, but once again DO NOT PUT WORDS IN MY MOUTH THAT MISREPRESENT ME.
Now please change the damage you have caused.
My point wasw Sceptic got his head handed to him on a silver planter and he wasn't man enough to admit it.
Now if management doesn't like this then delete my posts.
I think everyone agrees that there is a 'throw-out' action, #2 accumulator. I agree with the Throw-out action because in one of my Previous Lives, I was a Chinese Peasant who spent a lifetime beating Rice out of their Stalks with a flail (the nightmares still haunt me, my boss was sooo demanding). So I know a little about 'throw-out' and it has occurred on one or more occasions when I've held a Golf Club in my uneducated hands.
So? Is this thread about the cause of the 'throw-out'? If I'm hanging on to the club, and my body is rotating and me and the clubhead are being acted on by centrifugal/centripetal forces, then where else is the clubhead going to go?
Also, if we keep Calling it Centrifugal Force, and someday we discover that CF is not real, will we only be able to drive the ball 50 yards? I'm not willing to take that risk.
Gravity: Pulls the ball back to Earth after 180 yards. Without it the ball will go 285 yards like on the PGA because they stop gravity for tournaments.
Inertia: It’s what you feel when you have a cart buddy that doesn’t drive very well.
Momentum: Is what you need to get up a steep hill on a battery operated golf cart.
Magnetism: That is why balls turn right and land in the water. They are being pulled in by the Golf Gods.
Centripetal Force: That’s Spanish for Centrifugal Force. The force that POWERS the Golf swing.

Easy there, Rumbler. It was my mistake, and I apologize.
I was attempting to reply to your post, but I hit my admin 'edit' button instead of the 'quote' button. So, thinking I was extracting a quote for my reply, I was actually editing your post. As I recall, there was only one or two other lines, and I didn't think it was a serious issue. Nevertheless, I should have PMed you as to the error. Please use your edit function and restore the post to its original intent (or PM me the missing text and I will do it for you).
Again, my apologies. There was absolutely no intention to censure your post or change its meaning in any way.
P.S. In the interest of total clarification, I didn't add any words to Rumbler's post, i.e., "put words in [his] mouth", I just deleted some (and I think most of those were in golf_sceptic's post he quoted].
