Color Addition Subtraction: Joe Zerang

My phone cover is a white see through cover with a yellow M on it. When put under white light the M appears to be yellow. But, under red light, the M appears to be red. This happens because the yellow M absorbs the red light projecting on it.

Jumping salt Zerang/Gentile

With the tube, which is an insulator, we observed that the salt sticks to it. This happens because the insulator holds the charge and the neutral salt is attracted to the charge. With the pie tin, which is a conductor, we fount the results to be inconclusive because when we tried to test the salt, the salt did not really bounce off the pie tin.

Inertia @ Home Demo: Joe Zerang

I decide to demonstrating the cloth trick. To do this I first placed dinnerware on my dining room table with a cloth under it. Next I grabbed the cloth, and pulled down quickly. After that occurred, the items stayed in place. Inertia states that the tendency of an object to resist change in their state of motion. The items on the table resisted the change in their state of motion, after I pulled the table cloth, and stayed in place.

My mom didn't really have a lot to say except for the fact that you need to pull the cloth down quickly for it to be accurate. She hasn't learned physics since she was in school so I didn't expect a lot. What she said was a correct statement, but she left out any form of scientific evidence with her response. Overall I'd say her response was a 6 out of 10.

Vector Racing: Zerang/Gentile

To win the game one must click on the farthest circle to go farther. Newtons 1st law states that object at rest stays at rest and an object in motion tends to stay in motion. If I didn't click the circle it would stay at rest and not move. And if I kept clicking it the line would continue to move. In newtons second law he states that two unbalanced forces acting upon an object causes acceleration. This was clearly evident in our game because when the applied force on the vehicle is greater than that of the friction, the object will move and continue to accelerate.

In the winter these principles apply to our own driving because when the roads are icy the friction decreases because there is more skidding on the roads. Our cars produce more friction in the summer when the roads are dry and the tires are able to get more traction on the road. This is a big part of why you should be careful in the winter while driving because ideally the care will want to stay in motion. And if there is no traction then the cars tires won't be able to get traction on the roads. So when the car needs to be stopped, it will make it more difficult on the tires and the car itself.

Phaulty In Physics- Joe Zerang

    In this video we see multiple examples of how physics is defied. First we see Wile-E Coyote running from a bus and he's going faster than it. In real life it's rare that you see any animal run faster than a moving car. Next we see him run off a cliff but instead falling straight down like it would normally happen he continues running in the air. Here the laws of gravity are being defied because if anyone or anything were to fall/jump off a cliff, they would go straight down. And Finally we see him running in the air and straight into the neighboring cliff across the way. He then is basically plastered onto the cliff and then after about 3 seconds of being on the cliff he falls straight down... and lives. No one can stay plastered to a cliff and hang on for that long without falling. Overall in the clip the laws of physics are scrapped but the cartoon laws of physics are used. This meaning that no one dies after falling off a cliff and gravity basically doesn't exist when the characters are in mid air.

Gentile/Zerang: Projectile Motion photo

         This photo portrays projectile motion in multiple ways. First we see the quarter back project the football into the air, in a forward direction. When released, the ball is at a constant horizontal velocity until the receiver catches the ball. The vertical velocity is the only factor that is changing during this action.  If thrown correctly the ball should never decrease its horizontal speed, only when it hits the receiver does the speed of the ball change. Now having said that, sometimes wind as well as other weather elements, may effect the way the ball is traveling. For example if it is pouring rain out and the quarter back releases the football -due to weather conditions- it may slip, therefore projecting it in an awkward motion.

Motion Diagram Photo

As one photo would be unclear to the post starting in the bottom right corner reading to left and then continuing on the top you can see the motion diagram image that one would infer. The object is the Swimmer (Kristin) and her motion is through the butterfly stroke. After gliding through the water and coming up she uses her arms to pull her as her legs dolphin kick. The motions work together to create her acceleration. In creating this photo we went through a few decisions. We could have showed you just one photo but the collage makes it more clear in the upcoming motion. We made it by taping a video and then taking the side by side still frames and putting them together so you could see it all working together in one motion.
