Like many other students, I am looking forward to summer. One activity many people enjoy is water skiing! Water skiing has a lot of physics involved. The basics are essentially based on angles and gravity. When you get up from the start, your ski must be at a certain angle so that the water pushes down on the ski, creating a downward force that enables you to stand up (otherwise you'll just fall flat on your face). Once the forces up from the water and down on the ski are equal, you're set for t
Yesterday I was watching soccer on TV and saw Ronaldo notch a hat trick...yet again. However, I rather began to ponder the physics behind being a goalkeeper to stop shots - maybe not as perfect as Cristiano Ronaldo's. Physics can separate the good from the great goalkeepers.
Here are some factors in being a good goalkeeper:
1. Momentum- A goalkeeper must have his/her weight shifted forward, standing on their toes. When a shot comes, the goalkeeper will try to save the ball while moving
Recently I've had a little bit of a pickle fetish. However, one of the things that is inevitable for us regular pickle-eaters is the difficulty in taking of the lid of the jar.
One tip I have is to run the jar under hot water. This way the lid will become easier to turn. This is because metal has a higher coefficient of expansion than glass does. Thus, as the jar stays under the hot water, the metal expands a tiny bit, and the glass stays the same (I also find it easier to use my left hand
Kobe Bryant just retired after 20 years at the Lakers. As a player straight from high school into the NBA he has set many records and is arguably one of the best basketball players of all time. One thing that him and other basketball players are known for is his jumping (which might not be as good as it was 10 years ago). I figured this would be as good a time as ever to analyze his jumping skills in two videos - one of him jumping a pit of snakes and dunking a ball, and of him jumping over a ca
In my previous blog I discussed the physics behind Kobe jumping a pit of snakes, which I believe is legitimate (or at least physically possible). Now I'd like to discuss another instance of Kobe's famous athleticism: him jumping over a car moving towards him. This one seems fake to me in theory because the consequences of the stunt are too much to warrant him doing it. However, I still think it'd be cool to think about the physics of it.
This one is definitely faked. If you were t
The other day I was watching a soccer game, West Ham United vs Arsenal FC. I know I do blogs on soccer all the time but it's because I am just so fascinated by the things these players are able to do, hence why they are professionals. One of the players, Andy Carroll scored a bicycle kick, where a player flips himself/herself upside down with their foot in the air and kicking it over their head (sometimes referred to as an "overhead kick"). While this one was good, it reminded me of one from sev
