conceptual physics Projectile Motion

[@utubemusiccritic]

Excellent. Hewitt's use of humor and his ability to explain in simple terms make him a great teacher. Example: "Gravity doesn't take a holiday just because an object is moving."

[@ryangrafelman9927]

I actually saw an extended version of this course in my physics class, and he does an amazing explanation of projectile motion. I would love it if he were my teacher.

Where can I find the full courses?

[@SmileForPink]

Dang! I'm sorry! Everyone deserves a good Physics teacher. I mean, if it weren't for my Physics teacher, I might have HATED the class, but now, I've already signed up for a summer Space Camp! Just take my word for it, don't dislike the class, dislike the teacher, because Physics is AMAZING!! :D I had the same problem you have in Chemistry and I ended up miserable! :( I know how you feel!

My teacher is making me watch all of his videos!

@tubestick00 Actually what happens is that when the object is flying away is much more susceptible to air resistance and that most of the times is the reason for the the variations we usually see outdoors with bigger objects. Theoretically, we consider that the only force applied on the object is the gravity which is approximately 9.8 N. But do not forget that if there wasn't air resistance, even a plane or a feather would crash in the ground at the same time and velocity.

I'm starting to question physics after I watched this and remembered Mythbusters testing the myth about bullets fired vs. bullets dropped

[@ZoeJaymzQ]

Where can I finnd the whole video? I got such a kick out of it. I want to watch it again.

[@tubestick00]

a bullet fired from a gun hits the ground at the same time as a bullet dropped from the same height as the barrel of the gun. even though one travels nowhere bown vertically down, and one travels like 1000 yards away.

[@carultch]

Depends on how fast of a bullet. If it is so fast, that the speed is comparable to orbital speed of low Earth orbit, then it will take a longer time to land, because the ground would significantly curve away from it's landing point.

[@kbdalcour18]

This guy loves him some physics! Respect

[@Cyno7]

@tubestick00 can you explain precisely why this is?

[@Arghira]

so why a bullet doesn't fall like it was dropped ?

[@nathangable4058]

because they spin

[@ModKillr]

I think most people should take conceptual physics before you apply mathematics to it (at least for the most part). That way you understand that physics is fun before you know that it's tedious.

[@tubestick00]

gravity acts on it just the same. one happens to be flying away at high speed and ends up hundreds of yards away, but they both drop toward the earth at the same rate. in theory. it works in practice too, but there are obviously variables involved in the practical version that stop it being exactly the same time every time. they did it on that show mythbusters.

[@tbirdscience]

good video - would be better if he had a student catch each ball after the first bounce...that way, there's only one sound

[@isam1335]

I want him to change my physic lecturer !!!!

[@CraZyFAISAL]

The chuck Norris of physics that is

[@stevendinh677]

why does this happen????

[@MustangGTR2]

Richard Feynmann disciple.

[@xHASSUNAx]

? what are u talking about

[@MeTubeu333]

downish and outish,,... is that a fancy theory name? lmao

@RylyC The Conservatives are the best.

[@Armando17717]

loooool all A's

[@alxdotnet]

Is it just me or does this guy sound like (hell even behave like) Willem Dafoe?

[@1twozero1]

I hope everyone got a A because there definitely was 2 clicks
