Waking up

The hardest thing we do every day - waking up and getting out of bed. Newton's first law states that things at rest are likely to stay at rest unless acted upon by an outside force. Whether that force is our alarm clock, angry parents, or the panic of sleeping in a few minutes too late, it can be hard to get moving. Most days it's better to just lay in bed and hope that your homework does itself. However, Newton's law doesn't apply in the first few minutes after getting up - once you're in

James Cameron's Avatar

One of my recent favorite movies is James Cameron's Avatar, and while a lot of physics is a bit sketchy, some of it makes sense. The moon/planet the movie takes place on, Pandora, is a lot smaller than our earth. This means that gravity isn't as strong. So, while humans have to learn to deal with the debilitating effects of low gravity, the natural life has had plenty of time to evolve. All of the animals and plants are much bigger than their Earth counterparts. The people that live there

Running sneakers

I know the importance of shoes - running shoes, that is. Most track runners own at least two pairs, some trainers to practice in and spikes to run races in. Trainers are pretty much your standard sneaker, but they can get a lot fancier than that. Most of them have extra padding in the sole, which increases the time of impact between your foot and the ground. This means the impulse in your leg is much less, causing less injury to the runner. Running spikes have much thinner soles, which can

Drop it like it's hot

We can all remember that one time (probably more) when you dropped your phone. I'm probably most guilty of this crime against technology, and I'm always covering up my valuables with the giant bulky cases that could probably stop bullets. But how do these work? When your phone falls and hits the ground, the impulse is dependent on its mass and velocity. Since velocity increases the further the phone falls, a greater distance means a greater impulse. That's why it's safe to drop your phone

Hurdling is also pretty rad

All year I look forward to the Track&Field season because of one event: the 400meter hurdles, with which I have a love-hate relationship. A lap around the track, ten obstacles to jump... who wouldn't want to do it? Physics has helped me become a better hurdler. What a lot of people do when they start learning is they overestimate how high the hurdles are - I certainly did - and focus on jumping up rather than forward. This takes a lot more energy and slows you down a lot, since you're lau

Dragons are pretty rad, yo

NERD ALERT NERD ALERT Dragons are cool okay don't even pretend to deny it But the best part about dragons is they could totally exist. Barring of course the fact that they'd have to eat all the time and barely have enough air to breathe (more on that in like 4.6 seconds), we've seen (read: dug up) dragons who have existed in the past. Do you remember Petrie from The Land before Time? He was a pterosaur, a flying dinosaur with a wingspan up to 7.5 meters (which is probably like as tall

Just Can't Wait to be King

(I seriously feel the need to top Fiona's blog posts but that's just not gonna happen so bear with me) Something my parents will never let me live down is my obsession with the Lion King. From age 2-7, I apparently watched that movie every single day, without fail (I had such good taste, didn't I?). Today, I still love it, but there's a few inconsistencies that I've noticed between the world of the Pridelands and our planet Earth. Mainly, I'm referring to the song "Just Can't Wait to be K

The Best Unit in Gym Class

While I'm an avid runner and ultimate frisbee is my lifeblood, I still look forward to a singular gym unit each year - archery. Not because I'm particularly good (I'm pretty much always that one person who habitually hits the back tarp), but because I hate changing into sneakers and I do mildly enjoy feeling like Katniss Everdeen. Physics is embedded in archery. When the string is released, both it and the arrow move forward with a speed dependent on the strength of the bow's wood - a strong
