Vector Racing: Molly and Pearl
1) How does winning the game require you to apply Newton's 1st and 2nd laws?
The game applys the laws by showing the rate the car needs to accelerate and the direction it goes on turns, for it to successfully make it around the track without crashing into the sides.
2) How do these principles apply to your own driving especially in winter?
The games shows when a person needs to accelerate, decelerate, and maintain the the speed, especially on turns.

Pearl and Molly's Projectile Photo Project
Water being drained off a cup
This image illustrates a projectile motion because once the water is spilled out the cup, it makes a parabola motion. The water makes a slight curve once it is being spilled out of the cup.

Pearl and Molly's Phaulty Physics Philm Project-Tom and Jerry
Tom and Jerry
\
Occurrance of falling 1:28
Claim: In the cartoon, Tom and Jerry, Tom is seen falling from the top of the dock into the water. The motion that was impossible in the scene was at 1:28 when Tom was falling off horizontally at first, and then stops in the air for 22 seconds exact and then falling into the water below of him.
Evidence: A person cannot stay in the air for 22 seconds and waits to fall down. In the scene Tom goes horizontal to the left and then falls straight down after 22 seconds.
Reasoning: This segment could not happen whatsoever because a person cannot stay in the air for 22 seconds and floats there just waiting to fall down, and also Tom had to check if he really was in the air before he had fallen into the water. When a person falls they are falling horizontally and vertically at the same time.
