Hoverboards

Once thought to be a mere figment of science fiction, these floating skateboards are now all science and no fiction. However, as with almost all technology, it's not without its limitations. A couple of months ago, Lexus created the "slide" hoverboard, a piece of machinery that works because of magnetic force... meaning it only works on magnetic surfaces, an obstacle conquered by the creation of a custom skate park in Spain where most of the surfaces are made to be magnetic. Despite this limitat

Trampolines

Trampolines are always a ton of fun, but they're one of those everyday things a lot of people don't really question. it's one of those things people just take as common sense, but what makes them work the way they do from a physics perspective? how is it that they can propel a person so high in the air, and why is it that jumping on one somehow sends a person higher than simply jumping on solid ground? the answer is that on a trampoline, there is an extra force acting on you each and every jump.

Driving and Dynamics

After learning about and studying physics for a while, sometimes you just start thinking about how it applies to what you're doing right now. And while it may warrant a few odd looks from friends and family if you're like me and voice those sudden realizations, it can be quite fascinating, as there are some simple things that have some interesting explanations. Like how walking works because of a normal force the earth applies on you as your leg pushes down. As I was taking driving lessons one d

Don't try this at home

Conservation of momentum is a very important law. A rather interesting idea popped in my head earlier pertaining to this. Since momentum is conserved, wouldn't it be theoretically possible to lift off of the ground by hitting the ground fast enough with your hand? (Assuming you don't break something or get hurt.) If you're on a slippery surface or on something with wheels you can push off of a wall and slide in the opposite direction, so wouldn't something similar work vertically? Momentum is al

Space-Jumping Starships

With everyone waiting for December for the new Star Wars movie to come out in theaters, I thought I'd talk about some aspect of Star Wars in this blog. in this case, something that's common to a lot of works of science fiction: Spaceships, and the many capabilities they possess. First is their ability to simulate gravity. In the original Star Wars movies, the Empire utilizes massive space battleships called star destroyers, and despite them floating in space, the people on board seem to have no
