Avengers: Infinity War

Image
Infinity War is no doubt a fantastic super hero movie. Between the entertaining fight sequences and the engaging story the movie was extremely entertaining. Aside from all its upsides it lacked in solid physics and some of Newtons Laws are explicitly broken throughout the movie in multiple scenes.

Scene 1:
In the movies last climactic fight sequence on Wakanda multiple laws are broken. The first law broken is newtons third law, which is for every action there is an equal and opposite reaction. This scene being one for comedic relief where Bruce Banner (The Hulk) is in the Hulk Buster Iron suit and is running across the main battle field and trips. This scene breaks newtons third law because every time Bruce stomps he doesn't leave an imprint in the ground. This is a violation because the suit is massive and has to presumably have enough force to rival that of the Hulks, which means each time the suit pushes off the ground the same amount of force applied from the ground to the suit…

Armageddon

The movie Armageddon is about a scenario where an asteroid is plummeting towards earth and NASA has to think up a quick plan to save the human race. This brings up the question of what plans does NASA have for a real world Armageddon situation. NASA in fact just recently in April of 2019 created an asteroid impact exercise to help prepare key decision makers on the "what if?" scenario. The participants discussed economical and human consequences of the impact on a densely populated area like New York City. The main point of the exercise being how they would change the trajectory of the asteroid.

Eraser

Eraser, much like many 90's action films, is jam packed with corny dialogue, over the top fight sequences and of course Arnold Schwarzenegger. The movie is enjoyable to an extent if you're able to ignore the obviously horrible physics regarding the movies main subject, the rail gun. The rail gun in the movie is a weapon designed to shoot small aluminum bullets at the speed of light. The concept of the weapon is already extraordinary but the physics applied are even more crazy.

Here in the movie Arnold finally gets a hold of the rail gun and has a blast. In the scene we see Arnold rapidly fire the rail guns subsequently sending the bad guys flying while we see he takes little to know recoil. The fundamental problem here is if the bullets were to some how launch the bad guys, the force from firing the gun would also launch Arnold in the opposite direction. Applying the law of conservation of momentum we can calculate the velocity at which Arnold would go flying backwards. In ord…

Mission Impossible III

Image
Mission Impossible III is without a doubt an entertaining action movie and it fulfills its purpose in that way, but upon further analyzation of some questionable scenes we can see how realistic the physics in the movie are. 
In the first scene I would like to look at, Ethan Hunt (Tom Cruise) infiltrates a heavily guarded skyscraper by swinging from a neighboring building successfully landing and thus completing the mission. The question posed from this scene is whether or not Hunt could have made the jump. Some key elements to recognize are the distance between the buildings and the length of the chord used in the jump. Neither of the quantities are specified in the film but with some research of the building heights its easy to assume the buildings in question are around 200 to 250 feet apart or 61 to 70 meters. I can assume that the chord used in the jump would have to be at least the length of the gap so given that estimation I assume the chord is about 70 meters. So theoretically …
