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.
