And it turns out the Professor didn’t even realize he was under investigation. So he’s learning about this from the hearing too. So what this all adds up to, I think, is a performance so in line with what the lawmakers themselves wanted to hear, that at certain points, these Republicans didn’t quite know what to do with it. They brought in outside consultants, crisis communicators, experts on anti-Semitism.

This means that if an object A pushes another object B with a certain amount of force in one direction (action), object B will put the equal force on A, but in the opposite direction (reaction). When the air stored in the balloon rushes out through the narrow opening in the straw, it exerts a force on the car (action). The car, in its turn, exerts an equal and opposite reactive force and is propelled forward.
Balloon-powered cars are a fun way of demonstrating Newton’s Laws of Motion.
When the balloon is inflated it stores the compressed air as potential energy. When you let the air out of the balloon, the potential energy is converted into kinetic energy; this is the energy of motion or thrust, which is why the car moves. Because the air is pushed out rapidly backwards, there is a reaction force that pushes the car forward.
Why are my balloon cars driving crooked?
The car is already moving forward, so even though the balloon is no longer pushing it, it will keep moving until an outside force (friction) brings it to a stop. And so as Isabella and her colleagues at the college newspaper see it, there’s this overall chilling effect that occurs. Some students become fearful that if they participate in any demonstrations, they’re going to face disciplinary action. So fast forward now to April, when these student protesters learned that President Shafik is headed to Washington for her congressional testimony.

Trace the shape of the bottle top onto the roof, making sure that it is centered. Lightly score the fold lines on the “window, bonnet & grill” template. Now gently fold the cardboard on all these lines. Mark the window section so you know which side is glued to the roof.
Build a Balloon-Powered Car
Hence, it is proved that our balloon powered car is a good example of Newton’s third law of motion. BackgroundIt might not seem like it at first, but a simple balloon car is loaded with physics and engineering concepts! When you inflate a balloon, it stores potential energy in the form of stretched rubber and the compressed air inside. When you release the balloon, this energy is converted to kinetic energy—the energy of motion—as the balloon zooms around the room. Some of the energy is also converted to heat due to friction.
The engineering goal in this project will be to design, build, and test a car that is powered by nothing but a balloon. You want to design your car so it can travel as far as possible. For the ultimate test, you can follow a strict set of design rules used in the 2015 Engineering Challenge (see the Procedure for details). But back on campus, some of the students and faculty who had been watching the hearing came away with a very different set of conclusions.
Materials Required
The potential energy inside the balloon is converted to kinetic energy, or energy of motion, of the fast-moving air through the opening. Because the air is pushed out rapidly backwards, there is a reaction force that pushes the balloon forward, as shown in Figure 3. This principle comes from Newton's third law of motion, which states "for every action, there is an equal and opposite reaction." The main purpose of performing the balloon powered car experiment is to prove and learn Newton’s Third of Motion in a practical and fun way. This means we are going to learn about an equal and opposite reaction. In this experiment, when the air pushes back, the propelling force is created against the outside pressure of the air which makes the car move forward.

And this is not representative of the vast majority of the protesters in the encampment, who mostly had been peaceful. They would later hold a Seder, actually, with some of the pro-Palestinian Jewish protesters in their ranks. But those videos are reaching members of Congress, the very same Republicans that Shafik had testified in front of just a few days before. And now they’re looking and saying, you have lost control of your campus, you’ve turned back on your word to us, and you need to resign. There’s a video that goes viral of one of them shouting at Jewish students, go back to Poland, go back to Europe.
This is the same principle used in real and massive vehicles, rockets, and jets that shoot a high-speed stream of gases out the back of their engines, propelling the vehicle forward. The science behind the Balloon-Powered Car is so simple but impressive. When the inflated balloon is released, the air from the balloon rushes in to the straw because of the pressure created.
Of course, California has been influencing auto designers for decades thanks to the Art Center, just north of downtown L.A. But Dave Stollery, president of Industrial Design Research, laments this turn of events. He was the initial designer hired by Toyota Motor Corp. to develop Calty Design Research in 1973.

He believes it is still very important to have a studio that can pen futuristic designs away from the politics of headquarter-based design studios. He says he is saddened to see that Calty has become just another production design studio in Toyota's network, effectively working as a backup studio to Japan. Chuck Pelly, founder of Designworks/USA, says that the entertainment, computer and fashion industries help make California a leader when it comes to vehicle design. His studio, wholly owned by BMW since 1995, celebrated its 25th anniversary in 1997, making him one of the originators of the idea that California could be a design center. Mr. Pelly is not at liberty to discuss exactly what his studio has done recently, but does admit that "we enjoyed our heavy involvement" in the upcoming new 3-Series BMW.
Or they’re grinding our classes to a halt and we’re not able to function as a University. And set up an encampment in the middle of campus, no matter what the rules say. Well, I don’t think it’s just limited to college campuses.
