展現真實物理的直式影片：女子拿著小球走在黃金時刻的河岸，並把木船推離岸邊

提示詞

建立一段超寫實、電影感的 15 秒直式 9:16 影片，透過一個連續且可信的序列展現現實世界中的物理現象。場景：一名年輕女性在黃金時刻沿著河岸行走，手持一顆小球，並靠近一艘漂浮在岸邊附近的木船。0–3 秒，她自然地朝木船走去；她的腳步展現重力、重量、摩擦力、平衡、慣性，以及逼真的加速與減速。飄散的頭髮與衣物自然地受到風和空氣阻力的影響。3–6 秒，她輕輕將木船推入水中，並踏入船內。木船因她的推力產生逼真的反作用而向後移動，展現牛頓第三定律與動量守恆。木船加速時，她的身體因慣性而輕微移動，同時摩擦力與水阻力逐漸減弱木船的運動。6–9 秒，她將小球丟在木船內；重力使小球以逼真的加速度下落，依據其彈性與碰撞物理反彈一次，並因摩擦力而停下。9–12 秒，她將小球向前拋出；小球在重力與空氣阻力作用下沿著逼真的曲線軌跡飛行，而移動中的木船因動量持續向前行進。小球落在水面上，產生逼真的水花、漣漪、位移、表面張力、浮力與流體動力學互動。12–15 秒，木船持續自然地滑行，在身後形成逼真的航跡，同時水阻力與阻力逐漸降低其速度。整段影片中，準確模擬牛頓三大定律、重力、慣性、動量、動量守恆、能量守恆、摩擦力、加速度、減速度、碰撞力、彈性、質量、重量、空氣阻力、阻力、浮力、壓力、表面張力、流體動力學、位移，以及逼真的因果互動。每個動作都必須產生可信的物理後果，並具有正確的時間安排。物體在每一幀中都必須維持一致的質量、比例、位置、紋理與物理特性。使用逼真的水面反射、陰影、風的運動、自然的動態模糊、符合物理規律的光照、照片級寫實材質、電影感景深、流暢的攝影機運動，以及專業電影品質。不得出現不可能的運動、漂浮物體、瞬間傳送、突然且無法解釋的加速、物體穿模、解剖結構變形、物體重複，以及任何違反真實物理的情況。總時長必須恰好為 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.
