Hello, thanks in advance. I'm trying to make a near 100% solid carbon fiber wing. I'm vacuum bagging the top half of the wing and the bottom half of the wing separate. After making sure there is a thin 2mm gap b/w the center of both halves the goal is to put a very strong, thick epoxy between...

Thanks for the help and correction on units. How do you conceptualize what grams*cm^2 is. I can conceptualize mass b/c I can see a cubic cm of metal in my right hand, but I can't figure out what grams*cm^2 is. My ignorant guess is 4000 grams*cm^2 is equivalent to the force of 4000 grams...

I have done some extensive self study on MOI but I don't understand it's meaning in application. An example is imagine a stick of butter is dropped on the ground. Now ignoring friction and the other variables we can remove for learning purposes, let's assume the butter stick is kicked and it...

your post 13 doesn't make sense to someone ignorant to physics language. My latest attachment should be simple for anyone without your knowledge in this field to understand as well as I. If you don't mind posting the angle I was looking for in the previous diagram I would appreciate it. The...

What is the bounce angle of the ball in the attached picture. I am looking for the angle of the yellow angle. Thanks.

If a 45 degree block is moving towards a ball perfectly horizontal that ball is going to bounce off at an angle. My question is: what is the angle that the ball bounces off at in relationship to that perfectly horizontal motion of the block?

I was confused with 'reference frame' but I think I have it now. Let's forget about reference frames for a second and we only measure angles from the horizontal vector. The angled block smashes into the stationary ball with the block having an angle of 45 deg. The ball should then bounce off...

I'm confused by your terminology as I am a layman when it come to physics... question: are you saying that when a horizontal aimed laser hits a mirror angled at 45 deg that the light would bounce off at 90 degrees but if a 45 degree angled block traveling horizontal smashed into a ball that the...

So if an angled block titled back 5 degrees hits a ball moving horizontal then the ball will shoot up in a vector that is 5 degrees? For some reason I feel like this is similar to a laser hitting a 45 degree mirror and the result is a reflection of double that or 90 degrees. That is why I...

The block is moving horizontal towards the ball. The block is angled back 5 degrees so the ball should 'bounce' off the face at some angle. I believe this angle to be double the angle of the face.

I'd like to begin by ignoring friction and center of gravity at the moment if that is possible...and throw out any other variables until I get the larger picture down and then I'd like to ask for a discussion including those items... The picture shows a block moving towards a ball...similar to...

GOTCHA thanks...much thanks. I was thinking force was part of the stored up energy of a moving object. Now I see it is something applied to that object to change its momentum. Is the force the same for this asteroid hitting a massive object vs a small one?

This question may help me: Someone throws a baseball in deep space with no gravity and the baseball is constant. It hits a 1000 gram object and the object moves all over the place from the amazing impact... Now same baseball but it hits a 1million gram object and that object laughs at the...

I understand now by what you just stated thanks. Let me pose this since it is a backended way to get the force. Say the asteroid hit a stationary one flat surface to flat surface they meet perfectly aligned with no deflection and both are 1000 grams only one is traveling at 100 ft/s the other...

I'm still confused so let me put some more details out there. Let's again assume the moving asteroid is going 100 ft/s and to satisfy the poster thinking there is no other matter for relative measurement, let's assume there are two non-moving/stationary, very small bananas that we can use to...
