Chinese food

I was eating at a Chinese restaurant when several spoons flew off of the spinning table in the center. The inward frictional forces of the spoons were less than the required mv^2/r that would have kept the spoons spinning in a circular motion. The spoons therefore traveled in a trajectory off of the table that is tangent to the rim of the table. The mustard, on the other hand, had a larger normal force and frictional constant that allowed the mustard to stay on the spinning table.
In this perfectly drawn picture, the block has a inward frictional force that keeps it on the table. One spoon flies off of the table at tangency since it does not have enough frictional force. A spoon that has a smaller radius is also traveling at a slower linear velocity than the other spoon.

Relative velocity

I was sitting in the back of a pickup truck while tossing a coin up in the air. At first when I tossed it relatively low, the coin seemed to fall as if I was sitting inside of the truck. It fell straight down in my perspective because it had the same horizontal velocity of the car. To someone on the sidewalk, however, it would look as if it was moving in a parabolic motion. When I threw the coin higher, however, the coin encountered a wind force that slowed down the horizontal motion of the coin. This resulted in the coin landing on the road in back of the tailgate. This drawing illustrates the air flow.
When the tailgate is up, an air pocket is formed. This helps the truck to be more aerodynamic. If the tailgate is down, the air current will have higher pressure above the bed, increasing the drag of the truck in motion.

Circuits

Physics has shown that when wired in parallel, potential difference does not change among resistors. This would be the ideal way to wire a house because a large potential difference will not be needed. Rather than be shared among resistors in series, resistors in parallel will have the same potential difference as the power source. If potential energy is high, power will increase(P=IV). Parallel is also ideal for wiring a house because if something like a light bulb burns out, the rest of the circuit will continue to work. In series, the entire circuit would not work because the circuit is broken at the bulb. The best example of this are christmas lights. If one bulb breaks, you would have to check each bulb to see which one broke if it is wired in series. Finding out which bulb burnt out would be a pain.
