  3. I remember watching a Curious George episode as a kid that explained hot air balloons and it blew my mind
  4. This is an example of how magnets can be used for levitation, or hovering if you will. All this is, is simply the force of the magnet overcoming the force of gravity of the magnet and the liquid. In this way, a "hover board" would be nothing other than a force keeping something off the ground, which is just what a normal force is when you have an object sitting on the floor. However, using magnets for levitation is cool because you cannot see the force acting on the object, and the force can also be transferred through things, putting your hand between something being levitated by a magnet wou
  5. Pole vaulting is a very good example of the transfer of momentum. You are transferring energy from running down the runway into bend in the pole, and then that pole rotates after you jump, making the pole push you vertically. As a pole vaulter myself, I can say it is not all that complicated, it does not require you to be a physics student to get over the bar. However, it is super fun! It must be flying in the air and feeling the push of the pole behind you as you kick your legs up, hoping to get over that height you set for yourself. Common things people will say about pole va
  6. Personally I prefer building wall with working outlets and light switches over building a circuit in a lab, we do this in my Electric and Alternative Energy class. To me it just makes more sense, and I guess my time in physics is what gives me a good sense of how things like the electrical guts of a wall actually work. It seems like knowing how electrons flow through a system and through a switch is the basics for any circuit, functional or theoretical. However, I like that putting together a wall in this trades class that I take is actually quite challenging to understand still. Every basic w
  7. This is a video of a levitating frog. Apparently a 10 Tesla magnetic coil is being used to lift him. This is possible because pretty much all organisms have small amounts of ferromagnetic materials inside of them. And no this does not hurt the frog because the force is spread out over the entire body, but he is probably freaking out a little bit inside.
  8. Some magnets are more, uh, magnetic than others? Yes some magnets have a stronger magnetic force than others. Iron, nickel and cobalt atoms have more electrons orbiting in one direction than the other. This means they produce smaller currents like electromagnets. However, ferromagnetic metals like iron, nickel and cobalt like to line up into larger areas. These areas will line up, north to south like any other magnet if you put them in a strong magnetic field. You can even line up these areas yourself, maybe you've done this before, you take an actual magnet and rub it one way across a f
  9. Today at my locker, I took a stand against lockers everywhere. Every morning coming into school I visit my locker first thing to put away my jacket. I have been needing to wear a jacket for longer this year because of the ceaseless cold we've been having here in New York. To get to the point, I would come in from the cold wearing my jacket and go to my locker to put it away for the day. Like rubbing your socks on a carpet to induce a charge on yourself, the act of taking off my fleece jacket rubs it on my shirt, inducing the charge. This charge is then discharged when I touch my locker to hang
  10. I've been watching this gif for like 5 straight minutes
  11. Concise and profound, homerun.
  12. 1 Gauss = Mx/cm2 = 10-4T = a guy = /gous/ noun, a unit of magnetic induction 1 Tesla = measurements for magnetic fields = 104G = the SI unit of magnetic flux density = another guy 1 Newton = who knows? Wow look, these units are all named after some cool science guys, this is concurrent with many other units; Ampere, Kelvin, Pascal, Coulomb, Watt, Volt(a), Ohm, Farad(ay), Weber, Joule, and of course the Becquerel named after none other than Antoine Henri Becquerel. Seems like you gotta be a pretty smart science guy to have a unit named after you, wonder when we'll get the Ny
  13. This sounds very similar to a philosophical idea known as Occam's razor, you can look into it a bit, I don't trust myself to know enough about it to explain it here in the depths of the comment section.
  14. A common use of a brush motor is in a fan, for example the type that is used to keep my laptop from overheating. But what exactly is that preventing, and what does overheating do to a system such as a laptop? The fan helps to keep internal units cooled down, heat is created when there is resistance in the different hardware inside the computer. With all the units preforming very close to each other, a lot of heat can be generated. This is why keeping any appliance that generates a lot of resistance should be turned off when not in use, they are just draining unnecessary power and can crea
