For those of you who don't know, there is a video section of the Aplus site that features videos of physicsy origin. You can get there by clicking the word "videos" on the top blue bar of the site. http://aplusphysics.com/community/index.php/videos/view340vectordespicableme/ When I first saw this video, it was floating among intense brainteasing physics vids and real life examples of the science. I thought it deserved some defense for its place on the site, so let me explain what this despicable me mini clip has to do with physics. The most notable physicsfeature of the video is that the geeky character's name is Vector, as he explains both verbally and through body language. A vector quantity is a magnitude with direction. For example, velocity is a vector quantity. A velocity of 3 m/s to the right has both units (meters per second) and direction (to the right). 3 m/s alone, a speed, is not a vector quantity because even though it has units, it does not have a direction. We call this a scalar quantity. I hope that explains Vectors joke, "I'm committing crimes with both direction and magnitude!" If he were the evil Dr. Scalar, it would only have magnitude. Haha! Ha. Ha... Ha. ...And I didn't notice this before, but when Vector first comes into the scene he crosses his arms while doing the "vulcan salute," which is actually the nerdfighter salute (You know! Vlogbrothers on youtube). I thought that was really cool. I wonder if it wasn't even supposed to be there in the first place, but some nerdy producer put it in Not familiar with vlogbrothers? Do acquaint yourself via nerd humor: ...Just for the record, my favorite part of the movie is as follows:

Yes I know bowling is kind of boring compared to some of my other posts but there is actually a lot of physics behind it. One of the main topics or concepts behind it is kinematics. Bowling like anything in motion involves kinematics and forces. If you break it down, bowling is all about velocity and direction of that velocity. Often in bowling once you throw the ball you are looking to get a curve. The following is the general path of the ball and where the best spot on the pins is to get a strike. With this slight curve there are changes in velocity of the ball. Because velocity is a vector there is a direction. That direction changes as the ball curve changes. When the ball comes around the curve the velocity is at an angle going towards the gap between the head pin and the one just to the left or right of that depending on whether you are right or left handed. You want to get the curve because with this direction of velocity the ball will angle into the pins and will get you the end result you want. It is easier to get a strike that way then to just throw the ball straight.
