    I love you're videos! But I feel like this one could use a bit more explanation.... Because the sides of the cone are slanted at an angle, the weight of the cone was pushing out against the sides of the ramp. The diverging sides of the ramp then behaved as a "ramp" for each side of the cone as rolling the other way would have increased pressure on the cone and required more energy to push against it and lift its center of mass. Rolling "up" kept the center of mass relatively even until the drop, requiring much less energy. Gravity pulled it towards the path of least resistance.

    • dragonsage

      @kristafloral is the cone weighted in such a way that the center has more mass than the ends? is it like the center of the cone has more weight than its ends and therefore the center wants to fall down more than the ends wants to climb up, and the net effect is the center of gravity is pulled down but the ends of the cone end up climbing. Not sure if that makes sense.

  • NickMMM
    NickMMM 3 months ago

    It makes perfect sense. It works the same way a screw does, or a latch on a door does, or a handicapped ramp does. The angles on the moving piece act as inclined planes. The force of gravity pulls straight down, and the force of gravity on the object makes the weight of the moving object push against the stationary object, and it rolls up but the planes are actually moving "down" sort of. Think of the shape of the ramp on the door latch, and as you close the door, the force on the face of the latch, an inclined plane, pushes it back into the latch housing against the spring pressure, then the door hits the door jamb, it stops moving, and the latch is pushed by the spring pressure into the hole, latching the door. It's the same here. The downward force from gravity acting on the moving piece causes it to move to the direction of least resistance, which happened to be uphill in this case. I probably did a horrific job of explaining it, but yeah.

    This could have an application in sorting different sizes of spheres. If the sphere is large enough then it wouldn't be susceptible to the unique properties of this setup, but if it's small enough then it'll roll like the cone did.

    When I was a kid we had an old game based on this principle. It was just two rods and a big metal ball, you put the ball at one end where the rods are next to each other, and then you would have to slowly separate the other ends of the rods so that the ball would roll towards you, and you would get more a higher score the further you got it to roll.

  • jed stanaland
    jed stanaland 2 months ago

    I saw it as having a lower resistance to move in one direction than the other. In other words it would be easier to move in one direction than the other even though it seems like it should be going in a certain direction it would take more energy overall to move in the direction down because it would need to lift the bulge in the center and to do that it would need more energy than the simple letting it drop provided.

  • PietPadda
    PietPadda 3 months ago

    So it will eventually reach equilibrium and fall "down" just like the cylinder. The time it takes to change direction is dependent on the placement of the cone in order to manipulate its starting centre of mass. It's a nice display of the principle of conservation of energy.

  • Joe
    Joe 3 months ago

    This is a nice one, the clue is in the overhead shot .
    The widening of the ramp allowed the mass of the "cone" to overcome the slant. I bet a different angle or shape wouldn't work.

  • Wade Johnson

    I get it! Because of how the ramp and object are shaped it could go the other way.
    For those of you who don't understand the ramp is a V shape while the object is a smooth diamond like shape, because the object has that middle area that's further out ot it tried to go the other way it would get pushed up. But by going up the ramp where the ramp was wider the object's center of gravity was able to get closer to the ground.

    I always assumed that it falls "up" because the ramp has a V shape and the object also has a certain corresponding shape. so in order to move, the object (which seems to have a shape) moved towards the end of the ramp that's more open, thus moving "up".
    Just my assumption though

  • Broda Gaming

    And since the ramp separates as it gets closer to the catch, the cone shape makes it go from the fatter part of the cone to the skinny. If the 2 pieces of wood used were at the same distance apart, it wouldn't work this way.

  • tiafolla
    tiafolla 3 months ago

    This is a rare example where he did t explain it very well. The slats of wood slant down vertically, but they also spread apart from each other horizontally to the right. That’s why the cone-shaped weight rolls ‘uphill’-it’s center of mass drops because the rails spread apart as it rolls. There’s a whole variety of kids toys that use this method.

  • birdie
    birdie 2 months ago

    it has to do with the curvature of the cone. the sides of the ramp cause the cone to move upward due to the cone’s shape. it’s mass is toward the disc in the middle of the cone, so its mass is basically trying to fall in between the insides of the ramp, cone’s V shape makes it move upward while mass is falling down.

  • graydi66y
    graydi66y 3 months ago

    This wouldn't work if the 2 boards were parallel.
    The v shape causes the center of grafity to shift down because it's making contact higher up the cones on each side as it rolls towards the path of least resistance.

  • Happenstancially

    It’s not that weird.
    The wedge shaped ramp pushes inward on the diamond shaped dowel.
    The diamond shaped dowel applies outward force.
    The outward force and inward force are equal, until the angle of your ramp is factored in.
    It’s not complicated

      Because the vertical boards of the ramp that the cone was rolling on started out together and then widened. The cone’s large center was initially the only thing touching the ramp but as the width of the ramp increased it made room for the sides of the cone to fit into the ramp and roll into the slots…making it “appear” to fall down an upward slanted ramp.

    Yes the physics behind the experiment is sound, but things would've been better understood if the topview of the experiment was shown for longer. Because a lot has to do with the geometry of the 2 wooden pieces used. The incline on the rolling piece and the diverging track beneath create a mechanism so that as the rolling piece rolls, the point of contact with the track keeps moving out. This lowers the center of mass of the rolling piece.
