توضح هذه التجربة أنه عند وضع جسم ما في سائل، يزيح الجسم كمية من السائل تساوي كتلتها كتلة الجسم نفسه. علاوة على ذلك، فإن حجم السائل المُزاح يساوي حجم الجزء المغمور من الجسم.

  • التفكير خارج الصندوق وضوابطه

    التفكير خارج الصندوق هو التفكير الإبداعي من منظور جديد، لكنه يحتاج إلى ضوابط ليكون بنّاء. يستعرض المقال أمثلة على التفكير الإبداعي الناجح من نيوتن وأينشتاين وماكس بلانك، ويناقش أهمية تعليم الشباب التفكير النقدي بدلاً من التلقين، مع تحذير من التفكير الذي يخرق هذه الضوابط الأساسية.

    Conservation of linear momentum

    This demonstration explains conservation of linear momentum through cannon recoil. When a cannon fires a bullet, it recoils backward with much lower velocity due to its greater mass, illustrating the inverse relationship between mass and velocity. The post provides complete mathematical derivations showing that total momentum remains constant in an isolated system where net external force is zero.

    Torque

    This demonstration explains torque (moment of force) and rotational equilibrium. A force can create a turning effect that depends on both the force magnitude and the perpendicular distance from the pivot point. At equilibrium, clockwise moments equal counterclockwise moments. The post includes formulas for calculating torque with perpendicular and angled forces.

    Area Model of Partial Products

    Elementary math teachers know the importance of this model in teaching the concept of applying distributive property in area model.
    The idea is to break one large area (which represents the product of two numbers) into several pieces (products of smaller numbers), then to find the areas of the pieces individually, and finally add to get the area of the whole (the product of the given numbers).

    Newton’s first law demonstration

    Newton’s first law states that when net force is zero, objects at rest remain at rest and objects in motion continue at constant velocity. This experiment uses an air cushion scooter to eliminate friction, demonstrating that with zero net force (weight balanced by track reaction), the scooter remains stationary when at rest and continues moving at constant speed when given an initial push, until an external force stops it.

  • Simplicity is power

    In creating interactive educational tools, simplicity is power. A minimalist design doesn’t just look clean; it helps learners focus on what truly matters. Instead of overwhelming the user with unnecessary details, focus on providing a clear, interactive interface that mirrors the real-world experience.
