We'll be doing dangerous things like smashing a bunch of glass with rockets and talking about the farthest man made object and I'll explain why this is my last one. See you there and don't be tardy or it's a detention.

Thanks everyone for coming to my classes! Be good. Stay curious. Take care of your physical and mental health and I''ll see you around on the internet! Oh, and as always, please consider subscribing :)

So correct me if I’m wrong because you’re a lot smarter than me, wouldn’t the reason the astronaut goes the opposite direction of the hammer be because of the conservation of momentum not energy? And could be both I’m just asking

Mark if you see this please let me know i’ve heard from a lot of my friends I’m not the only person that has the same dream of being in a fight and not being able to punching somebody and feeling like you can’t move sort the same way that guy is moving in the space station with zero gravity is exactly that feeling how weird is that and maybe it’s our brain remembering where we came from??????????😂 just a thought

Mark, perhaps its been pointed out before, but I just wanted to clarify that force (Ft) is _inversely_ (not directly) proportional to time (Tf) ≈ Ft 1/Tf!

Wouldn't a mars rover be the furthest man made object from Earth? Seeing as how Mars at its closest approach to Earth is still 38.6 million miles away..

So there is a suit that has sold fabric webbing in between the arms and legs, I have seen a man fly like Super Man across the sky in one of theses suits.... So my best guess would be to use that suit.

it's like when you driving fast in a plain road, you will have a hard time stopping the car. But when you driving fast up a hill, you can almost stop instantly by a lite break.

Growing up one of my random thoughts were similar. That is you were falling and landed on some crazy vertical slide you could just slide out of it as the transition from vertical to horizontal would allow the decent. Love the videos, can't believe I didn't see these lessons till now.

From memory *The holes are to allow the sign to shear off if you hit it with your car. *Not sure about the doors *The nuts... I would think it's to allow the driver to be sure none of the lugs are loose? *I heard the scales thing as well, but I've seen videos that, if I recall, your car creates a disturbance in the magnetic field generated by a coil buried in the pavement. *I think it was a how it's made video, they had glass microbeads in the paint used on the signs. Obviously, the more reflective the material used the better the end result. Something about the bead consolidating light from multiple angles. *Water barrels. Again for car crashes. They decelerate your vehicle much like an air bag. The barrel bursts on impact and absorb some of the force of the impact. I've not heard of them being filled with sand though.

If you watched this and think it was interesting then you might want to try your newfound knowledge out on explaining the physics that allows someone to do a 40 feet belly flop into a kiddie pool with two feet of water in it and walk away unharmed. Here's a hint: It has to do with the physical dimensions of the pool, and yes the water extends the time aspect of the impulse, but still two feet shouldn't be enough to . To large a pool and you will get seriously hurt or even killed. Fail to get the belly flop perfect and it's equally bad. The physics behind it is quite interesting, at least as long as it's someone else who is doing the jump. I sure as H wouldn't want to try it myself, seeing someone else doing it is enough excitement for me.

7:47 you said voyager was 13 million miles away, but it's actually 13 billion. Random facts for anyone uninformed: 1 AU ~= 93 million miles, and it (voyager) is MUCH farther out than 1 AU :D (1 AU or astronomical unit is the mean (average) distance between Earth and the sun)

Going to be a little Geekie, but with the idea of throwing the wrench you'd need to be careful would probably need to throw underhand as over hand would likely just spin you in place. The thrust generated from pushing against a wrench would be too far from the center of mass if thrown overhand.
