Whemp, video doesn’t lie. I guess the first law of thermodynamics is wrong.
Well it is now.
First law of thermodynamics: You don’t talk about thermodynamics
Third law of thermodynamics: Someone yells stop, goes limp, taps out, the dynamic is over.
Fourth law of thermodynamics: Only two thermos to a dynamic.
Fifth law of thermodynamics: One dynamic at a time
Sixth law of thermodynamics: No shirts, no shoes
Seventh law of thermodynamics: dynamics will go on as long as they have to
Eighth law of thermodynamics; if this is your first thermo, you have to dynamic.
Man i miss troll physic.
Bring back “Look around you”
What are birds?
We simply don’t know
It’s classified.
New albumen! It’s out now!
I’m a big stupid and can come one smart explain why this doesn’t work in reality?
The magnet is not pulling the car, the hand holding the magnet is pulling the car.
Okay. Maybe even dumb it down a little more? Just in case someone out there still doesn’t get it. Not me, I get it. Just someone else might not, and what about them you know?!
When the magnet got glued to the car, it became part of the car so it wouldn’t actually move. The reason it moves when it isn’t glued is because the hand keeps pulling the magnet away
Imagine a string instead of two magnets. If the hand pulls the string, the car moves. If the string is tied to the car?
Magnets transmit force, they don’t magically create energy. It takes energy to move the car, not just a static force being present. It’s the same as taping a stick to it without the magnets. Unless someone pulls on the stick (or magnet), no energy is entering the system and no work can be done.
Time to draw some free body diagrams!
Actually it would be the same force on the car if you removed the arm holding the magnet and placed a block of wood in the space between the magnets. It’s a static system
Just like the hanging magnet is pulling on the car, the car magnet is also pulling on the hanging apparatus. Unfortunately for the car, the apparatus is attached to it, so it all cancels out.
It is both pushing and pulling at the same time.
It doesn’t work because, while the front magnet is pulling the car magnet forward, the car magnet is also pulling the front magnet backwards and the front magnet is also attached to the car, so it cancels out.
Its a remote control car
It’s probably just on a slight incline. Much simpler
I haven’t been able to locate the link again, but the full video shows they’re using a hairdryer to push it.
In simplest terms, the two magnets are trying to pull toward each other equally. But when you glue them on the board, that glue holds the magnets apart, and “pushes” them the same amount that the magnets “pull” towards each other, hence no movement.
There would only be a movement if one side was pulling more than the other. The hand is providing that imbalance at first which moved the car.
Magnet want to pull and stick to each other of the different pole. When it glued to the car, the one on the cardboard will want to move toward the car and the one on the front hood will want to move toward the cardboard. The force cancel each other out so no movement will happen.
I know a there are a lot of replies already, but I feel like the best way to explain is it’s similar to trying to push a car while you’re in it.
Ok when not glued: both magnets get pulled to each other. The hand has to use some force in order to stay in place, so the car moves.
When glued: both magnets still get pulled to each other, but now the force is cancelled out since the force that would pull it forward also has to be used to hold the other in place.
Basically, as much as the magnet on the car is pushing it forward, the magnet on the stick is pulling it back and it doesn’t go anywhere.
The magnets are not pulling it forward.
I think it’s the same as trying to give a sailboat acceleration by trying to blow the sails while standing on deck.
Somebody should send this to Elon Musk.
Why, I don’t get it.
Oh yeah, it’s big brain time
No one is commenting about the magnet on the back of the car and possibly a magnet in the person’s hand causing the rear magnet to repel against the hand magnet?
