the italien job

i was watching the italien job again this weekend and my favorite part is the speedboat chase through the venice canals. meanwhile, the safe is actually underwater, and the guys are breaking it open to get the gold out. you know why they do it underwater? because gold is very heavy. and underwater, buoyant forces equal to the mass of water the gold displaces. Therefore, the net force is the weight MINUS the buoyant force. ha lighter. smart people right?

Family fair

I hope everyone went out and worked at the family fair or spent lots of money. did you notice all the physics there? on those kiddy rides, kids get in the seat and are spun around the center, with a force equal to the mass of the kid(s) and seat times the velocity squared they're going divided by the radius of the ride. The force is directed radially inward and the velocity is always tangent. Wow, it just so happens that we were reviewing that this week. Don't you love physics?

Baseball

So I was at a family party, chilling outside with my cousin and my uncle. They were throwing around a baseball and I was sitting on the side watching, laughing and listening to music. Then it was like BAM! woah. projectile motion! Now that's something we haven't studied a while in physics. The whole, x velocity remains constant and y velocity changes with the kinematic equations due to acceleration of gravity. And guess what? That was in the first question of the review problems. Physics is all around, it's important to review so you can remember all those different phenomenons going on.

MRI

This week I had to get an MRI, which I still don't what it stands for. But anyway, as I was lying down, I looked up at the tunnel thing (which is like two inches from your face after they slide you in, which makes anyone claustrophobic) and it had this weird "x" shaped hole. On the side, there was a label that said a laser sometimes shoots out of there and not look into it. It gave the wavelength of the ray (I think it was 500 nanometers). So I got all excited! I could calculate frequency, Energy of the photons, and all that awesome stuff we've been learning recently. Unfortunately, big numbers like that were too big for my brain so I fell asleep instead. But physics is all around us!
