Weightlessness

Image
Apollo 13, the movie, was made after the awesome space mission that went down in history in 1970. The producers and cast recreated this mission to the best of their ability, and did a phenomenal job of portraying weightlessness, something most media fails to do. How did they get this so spot on? What did they do right? Well, for starters they actually did achieve weightlessness, rather than just pretending to. Props to them! 
Now, lets talk about the science! Weightlessness is an awesome and important concept, but it can often and easily be misinterpreted
Misconceptions of Weightlessness
- Astronauts become weightless because there is no gravity in space







- Zero gravity means there is no gravity present 






Fixing the Misconceptions Okay so first of all, if you think there is no gravity in space... please know that you're wrong. I am only kidding with my aggressiveness; however, I am serious when I say that there is definitely gravity in space. If you forget about gravity being in spac…

Avengers, Would Newton Approve?

Avengers: Infinity War, a movie loved by many, myself included, is a huge deal when it comes to the superhero world; however, anyone interested in physics watching this movie will notice some
flaws that other people may not. Of course, physicists know that they are superheros, with superpowers so the hopes were not that high for accurate physics, but there are some cases in this movie where honestly, it's just a nope from me.


Let me start by explaining the topics I will be covering in this blog: Newton's Three Laws of Motion.  Isaac Newton came up with three laws of motion that are very important to our everyday lives, even though we may not acknowledge them.

Newton's 1st Law of Motion:

Also known as the law of inertia, the first law states that an object will stay at rest or in motion in a straight line, unless acted upon by an outside force. Newton's 2nd Law of Motion:  Net Force= Mass x Acceleration.  Which tells us, any acceleration has a net force, vice versa.  New…

NASA's Plan to Combat Future Asteroid Threats

Image
So first of all, what is an asteroid?  An asteroid is a rocky, airless remnant from the early formation of our solar system, about 4.6 billion years ago. Most asteroids stay between Mars and Jupiter in the main asteroid belt, and right now we currently have count of almost 800,000 of them. Size definitely varies, with the biggest known asteroid, Vesta, coming in at about 329 (530 km) miles in diameter, and some others measuring less than 33 feet (10m) across. Something very interesting to note is that the total mass of the asteroid belt combined is less than the Earth's moon.  ("NASA, NASA")



That's cool and all, but why do we care about asteroids? Asteroids are super important to us for multiple reasons, but probably the biggest is how they impacted the earth 65.5 million years ago. One asteroid is known to have wiped out the entire dinosaur population! This particular asteroid is thought to have been between 10 and 15 km wide, and with such a high velocity, created a …

You Have Been ERASED... And So Have The Physics...

John Kruger, considered to be the best of the best in the U.S. Marshall witness protection agent world, has a big mission... well actually with all of the weird unnecessary plot twists in the movie, I would say he has a couple of averagely sized missions...anyways... John is supposed to accomplish two main things in this movie: keep Dr. Lee safe, and stop a major arms cooperation from selling hundreds of rail guns to terrorists. (Dr. Lee is the one with the proof, so she kind of played an important role in the movie )

Side note: Personally I did not like the way the producers portrayed Dr. Lee as a character. In the beginning of the movie it seemed as if she was going to play a huge role in this movie and remain that way throughout; however, it was like John dropped her off and she hid for half the movie. That was kind of lame, not going to lie. 
Now the important content, the physics. Not only did the movie have a mediocre plot, it also had awful physics, for multiple reasons.

Mission Impossible 3 Review

Image
Mission Impossible? Well the title is fitting, isn't it? Mission Impossible 3 is an intriguing film when it comes to evaluating physics, because some of the scenes seem so incredibly wild.

            First, let's take a look at Ethan Hunt's incredible swinging techniques. Clearly, this was a full-proof plan, for he even calculated it on the window with a marker before-hand, but was Ethan running fast enough to make it to the next building?  The first building was a good 226m tall, where as the second building was about 162m tall, and the two buildings are roughly about 48m apart. It was obvious that Ethan was doing his best to run as fast as he could, so we can assume that he was sprinting. According to the internet, the maximum speed for a man sprinting is about 20-25 mph. How about we give Ethan the benefit of the doubt and say he was sprinting 25mph (11.2 m/s) ? Also, Ethan really did not jump, he just kind of ran off of the building, but we will say the ang…
