I've been seeing some action films recently and noticed how frequently explosions are utilized in dramatic sequences. Although I like the excitement, I've been wondering about the physics involved in these explosions. In most films, we witness huge explosions with cars or buildings disintegrating, but I wonder how realistic these depictions actually are.

For example, in movies like The Dark Knight or Fast & Furious, the explosions are often huge and result in large shockwaves and flying debris. However, in reality, how much of that would actually happen? I’m aware that explosions in movies are often exaggerated for visual impact, but how much of that exaggerated physics still aligns with real-world laws, like the conservation of energy and the way pressure waves travel?

I came this website:https://aplusphysics.com/comm unity/index.php?/topic/12766-alteryx-course-understanding-the-physics-behind-the-gravity-movie-scene/&do=findComment&comment=15788 and still excited to know behind the scenes of Physics of Explosions in Movies.

I’d love to hear your thoughts on this. Are there any movies you’ve seen that got explosion physics right, or at least got close? Any resources or articles that dive into this would be great too!

Looking forward to the discussion!

Cheers,

I recently watched the movie "Gravity" and was fascinated by the realistic depiction of space. One scene that particularly caught my attention was when the characters use their thrusters to navigate through space. I'm curious about how accurately the movie portrayed the physics of such maneuvers.

I also check this: https://aplusphysics.com/community/index.php?/blogs/entry/29979-another-example-of-physics-in-a-moviealteryx But I have not found any solution. Could someone explain the real physics behind using thrusters in zero gravity? How close is the movie's depiction to what actually happens in space? Any insights or explanations would be greatly appreciated!

Thanks!

After watching the movie “Interstellar,” your assignment is to pick two different story / plot points or phenomena demonstrated in the film and analyze the physics involved. Is what they demonstrate consistent with current theories? Why or why not?

Post your findings in the APlusPhysics Community, Forums section, under TV & Movie Physics by responding to the Interstellar thread. You can create two separate responses, one for each topic, or combine them into a single post. Respond to the posts of at least two other students.

    Lets say that Goblin dropped her rom a height of 50 meters.

   She began falling from rest at an acceleration of 9.81m/s^2.

   She reached terminal velocity about half way down and had a final velocity of about 55m/s

So, when the web hit her she was traveling roughly 55m/s and the hard stop was too much fore her neck to bear and snapped it. That....is how she died.

So in episode 1 a titan comes over the wall and begins to eat the protagonists' mother. As the monster bites down, the mother literally explodes with blood flying in every direction. I was recently told that the average human body has less than 2 gallons of blood in it. If you watch the video you will see that there is WELL over 3 gallons shown.

So not only does the volume of blood defy reality, but the force of which it explodes is like a Michael Bay movie. When someone gets cut severely, it may squirt but it will mostly just leak and get all over. Not in this show. The blood comes flying out at speeds nearing 70mph. So yeah, I don't see why this show is such a hit because it is so inaccurate!

If you want to learn more about Dr. Kakalios, he was highlighted in a three-part interview last year as part of the Physics In Action podcast. You can download these and other past episodes from the APlusPhysics Podcast Page.

His book, The Physics of Superheroes, is also a terrific introductory-level book that examines physics from the standpoint of a variety of comic book superheroes. I highly recommend it, and have also had a number of students read it with 100% positive reviews.
