Ultra-réaliste démonstration de physique en laboratoire

Create a cinematic, realistic educational video set inside a modern university physics laboratory. A confident male physics professor walks into the classroom carrying a coffee cup and a notebook, while students sit attentively in a large lecture hall. The scene then transitions to a hands-on physics experiment where the professor and a group of students gather around a transparent inclined track. A small metallic ball is carefully placed on the track, creating a clear visual demonstration of motion, gravity, acceleration, and energy. Show detailed close-up shots of the transparent rail, metal ball, students observing closely, and the professor guiding the experiment with natural hand movements. Use smooth camera movements, realistic depth of field, natural facial expressions, and authentic classroom interactions to make the experiment feel engaging and believable. Include cinematic laboratory lighting with soft indoor illumination and warm sunlight entering through large windows. End with the professor working at a laboratory table during golden-hour lighting, surrounded by scientific equipment, creating a thoughtful and inspiring academic atmosphere.
