    Newton was really the true scientist who had changed the thinking habits of the people. Before him, people were facing the same kinds of problems but no one tried to find the reasons behind these happenings. I salute Newton for giving us a sense of thinking and imagining.

    Sometimes, I feel Newton's third law of motion is forced to suite a narrattive, even when it doesn't necessarily explain a phenomena. It is hard to explain the applicability of the law in relations to the motion a bicycle. I think it is because the bicycle moves vertically, meanwhile the law suites horizontal motion. It better fits the working for a rocket going to space. But for a bicycle I find I awkward. Great video by the way

    One question: How does the bike stay upright? When a person mounts a bike and stays still (no kickstand or legs, just the two bike tires) they fall over. But, we said person is moving it is really easy to stay up. However, no new force is applied in the left/right direction to help keep the bike up? So how does the bike stay up while it is in motion?

    • @MrCrazytodd
      @MrCrazytodd 9 років тому +2

      momentum... it is too "focused" on moving in one direction, that is to say it alleviates the potential of falling left or right like a domino. Remember that there is also air resistance... aerodynamics keep it aliened as well, much like an arrow flies straight and only straight, until an external force (such as wind or gravity) interferes. I hope this helped in answering your question.

    • @blasttrash
      @blasttrash 9 років тому

      Todd Gobbett But why do three wheelers stand upright even if they are not moving? why only vehicles having below 2 wheels fall down when not in motion? I mean my bicycle falls down but my car or tricycle doesn't when in rest.

    • @MrCrazytodd
      @MrCrazytodd 9 років тому +1

      blasttrash Because then the weight is more evenly distributed throughout the 3 given points. The tricycle has more surface area to support its centre of gravity. A bicycle or unicycle does not.

    • @JulieStardoll
      @JulieStardoll 7 років тому +3

      I believe the speed of the bicycle does not allow it enough time to be pushed over by air on either side. Or in other words, the force applied in propelling the bicycle forward is more than the force applied by the air on either side. Then there's also the fact that the centre of masses of you and the bicycle are properly aligned I guess. Todd Gobbett gave a pretty good explanation as well.

    • @anteeee8
      @anteeee8 7 років тому

      gilgamesh2399 actually these are all bad explanations
      an arrow flies straight for a complitely different reason, air drag and gravity always work on it in flight
      bicycle is not "too focused" on forward movement, there is no such quantity in physics
      this is explained via precession, which is a very comlex mechanical concept that relies on the conservation of angular momentum
      a frisbee flies, a spinning ball changes direction, a spinning top stays stable - all due to precession
      thank you for asking questions
      btw to anyone who got it wrong: props for trying, it is better than not analysing at all. :)

  • @anonymoususer9837
    @anonymoususer9837 5 років тому +10

    Nice video, but something missing or not directly stated, for Newton's 1st Law:
    Objects at rest tend to stay at rest *unless acted upon by an outside force.*
    Objects in motion tend to stay in motion with the same velocity (velocity is speed with direction, and depending on your frame of reference, it can be negative) *unless acted upon by an outside force.*

    O ato de iniciar a pedalada em uma bicicleta demonstra-se potencialmente mais desafiador do que manter uma velocidade constante, em virtude de fatores que incluem a necessidade de superar a inércia inicial, equilibrar-se adequadamente, ajustar as marchas de maneira pertinente, lidar com resistências iniciais e coordenar meticulosamente os movimentos. Tais desafios, entretanto, tendem a ser progressivamente superados por meio da prática sistemática e da aquisição de habilidades específicas associadas ao processo inicial de movimentação.

  • @Driamer
    @Driamer 11 років тому

    That video gave the impression that the energy from the bouncing ball is all delivered to the floor that in return sends it back to the ball, is this accurate? I don't really have knowledge about physics but I have always thought that the bouncing ball bounces because it has less resistance to keep the energy in itself by contracting and releasing it by expanding. This also explains why the doesn't bounce off a surface that is softer than the ball itself. Please correct me if I'm wrong.

    • @penguin_reader_yt9510
      @penguin_reader_yt9510 9 місяців тому

      I believe it is a combination of both. Granted, you've probably learned this by now, since this comment was ten years ago, but for anyone else with the same question:
      There are two parts to this. First, the ball delivers its energy to the ground, and the ground pushes it back. However, how much the ball actually bounces does depend on factors such as softness of the ground (softer absorbs more energy) and resistance of the ball, e.g., material and density. The second part is why rubber bouncing balls bounce better than hard, dense baseballs or soft, barely dense cotton balls.

    in the 3rd law ,is it an equal and an opposite reaction, or a reaction thats equal?they spoke differently in the 17th century than we do now.so did Newton word the 3rd law badly, or since we percieve/live in a 3 dimensional world are there two reactions to the original action?i.e. an equal reaction and an opposite reaction.
    i always thought the 3rd law was worded badly. it should be "an equal opposite reaction",not "an equal and opposite reaction".
