船上连续物理实验短片

创作一段超写实电影感的15秒竖屏9:16视频，通过一段连贯、可信的完整镜头展示现实世界的物理规律。场景：一位年轻女子沿河边行走，手里拿着一个小球，在黄金时刻走向岸边漂浮的一艘木船。第0–3秒，她自然地走向木船；她的脚步体现出重力、重量、摩擦力、平衡、惯性，以及真实的加速和减速。她的散落发丝和衣物随风和空气阻力自然飘动。第3–6秒，她轻轻将木船推入水中并踏上船内。木船作为对她推力的真实反作用力向后移动，体现牛顿第三定律和动量守恒。随着木船加速，她的身体因惯性略微晃动，同时摩擦力和水的阻力使木船的运动逐渐减慢。第6–9秒，她将小球放在船内；重力使其以真实的加速度下落，依据其弹性和碰撞物理规律弹起一次，最终因摩擦力而停下。第9–12秒，她将小球向前抛出；小球在重力和空气阻力作用下沿真实的弧线轨迹运动，而移动中的木船因惯性继续向前。小球落入水中，产生真实的水花、涟漪、水体位移、表面张力、浮力以及流体动力学互动。第12–15秒，木船自然地继续滑行，随着水的阻力和拖曳力逐渐降低其速度，在船后形成真实的尾流。在整段视频中，准确模拟牛顿三大定律、重力、惯性、动量、动量守恒、能量守恒、摩擦力、加速、减速、碰撞力、弹性、质量、重量、空气阻力、拖曳力、浮力、压强、表面张力、流体动力学、位移，以及真实的因果互动。每一个动作都必须有可信的物理后果和正确的时序。物体在逐帧之间必须保持一致的质量、比例、位置、质感和物理属性。使用真实的水面倒影、阴影、风的运动、自然的运动模糊、符合物理规律的光照、写实材质、电影化景深、流畅的镜头运动以及专业电影级画质。禁止出现违反物理规律的运动、漂浮物体、瞬移、无法解释的突然加速、物体穿模、人体结构变形、重复的物体，以及任何违背真实物理的情况。总时长精确为15秒。

Create an ultra-realistic cinematic 15-second vertical 9:16 video demonstrating real-world physics through one continuous, believable sequence. Scene: a young woman walks along a riverside carrying a small ball and approaches a wooden boat floating near the shore during golden hour. From 0–3 seconds, she walks naturally toward the boat; her footsteps demonstrate gravity, weight, friction, balance, inertia, and realistic acceleration and deceleration. Loose hair and clothing react naturally to wind and air resistance. From 3–6 seconds, she gently pushes the boat into the water and steps inside. The boat moves backward as a realistic reaction to her push, demonstrating Newton’s third law and conservation of momentum. Her body shifts slightly because of inertia as the boat accelerates, while friction and water drag gradually reduce the boat’s motion. From 6–9 seconds, she drops the ball inside the boat; gravity causes it to fall with realistic acceleration, bounce once according to its elasticity and collision physics, and settle because of friction. From 9–12 seconds, she throws the ball forward; the ball follows a realistic curved trajectory under gravity and air resistance while the moving boat continues forward because of momentum. The ball lands on the water, creating a realistic splash, ripples, displacement, surface tension, buoyancy, and fluid-dynamic interaction. From 12–15 seconds, the boat continues gliding naturally, creating a realistic wake behind it as water resistance and drag gradually reduce its speed. Throughout the entire video, accurately simulate Newton’s three laws, gravity, inertia, momentum, conservation of momentum, conservation of energy, friction, acceleration, deceleration, collision forces, elasticity, mass, weight, air resistance, drag, buoyancy, pressure, surface tension, fluid dynamics, displacement, and realistic cause-and-effect interactions. Every movement must have believable physical consequences and correct timing. Objects must maintain consistent mass, scale, position, texture, and physical properties from frame to frame. Use realistic water reflections, shadows, wind movement, natural motion blur, physically accurate lighting, photorealistic materials, cinematic depth of field, smooth camera movement, and professional film quality. No impossible movement, no floating objects, no teleportation, no sudden unexplained acceleration, no object clipping, no distorted anatomy, no duplicated objects, and no violation of realistic physics. Total duration exactly 15 seconds.
