Transportation in the news
That's a force.

What provides thrust in a golf cart?
Battery powered motor!

What kind of transportation system (though not one we've really discussed) has been all over the news over the last year? Hint: it involved a lot of scary standoffs on US soil.
A pipeline!
100
What force is nearly ALWAYS acting on transportation
What is Gravity (the exception would be deep, deep space)
100
What zone of transportation does a bicycle move through?
Land

In addition to moving around humans, what is the most important benefit of transportation?
moving food!
200
What vital suspension system is in place for the transportation system of horseback?
A Saddle. Try riding a horse without one. You will never walk again.

Recently an idea has been proposed for a superfast rail system, that could carry passengers across the country in a fraction of the usual time.. what is this system called?
HyperLoop
200
For space exploration to work, space shuttles must have enough of what force in order to overcome earth's gravity?
Thrust
200
How are moving through the zones of air and sea similar?
Both experience drag
200
Why do skis allow for easier movement through deep snow?
Skis redistribute your weight over a wider distance, and reduce friction allowing you to slide over the snow instead of stomp through it

Why is the structure of a ship or boat so important to its function? Don't say not sinking. That is obvious.
The design of the hull of a ship can be varied for different purposes. Hulls designed to carry a large amount of cargo are wide and sweeping, whereas a ship designed for speed will have a much more narrow shape to better cut through the water.

We all know what airforce one is, but what is Marine One?
Marine one is a heavy duty helicopter used by the president for shorter flights from the white house to nearby airfields.
300
A cruise ship must overcome what force for forward motion?
Drag!
300
How is space unique among the four zones of transportation?
-very little (if any) friction or drag -while gravity exists, it has a VERY different impact on transportation -all vehicles in this zone require life support to sustain human pilots I will take any of these or an answer I deem good enough.
300
What is the most utilized form of transportation?
Walking. Ha.
400
How does a train utilize control?
While a train is on predetermined tracks, it is kept on those tracks by regulating speed, and can move direction by use of railroad switches. While its movement is limited to track available, this is still an example of control.
400
What company recently announced they were going to send some millionaire tourists to the moon?
SpaceX
400
How is friction different from drag?
Drag is rubbing or contact between a solid and a liquid or gas (fluids) Whereas friction is rubbing between two solid objects.
400
Energy efficiency is a major part of today's economy. If shipping a high weight load, which zone would be most cost effective (energy and cost wise) for transportation of goods? Why?
The Sea! While it may take longer sea transportation remains the most cost effective while still being the most energy efficient (currently).
400
How do we measure the efficiency of a transportation system?
Comparing the speed and capacity (how many people/goods it can transport) to the cost (can be in form of expense or pollution)
500
How does the propulsion system of a helicopter work?
Helicopters have a motor that spin the rotor. The blades of a helicopter are designed to create lift, leading to flight.
500
Over the last few years shipping companies have been remapping their trade routes over sea, due to the opening of new routes around the world. Where are these new possible shipping lanes coming from?
Melting ice at our norther and southern poles are creating new openings for shipping. Yep, I found a way to link it to climate change. Which again, IS A THING. 100%
500
How does lift work?
the shape of an object allows (at high speeds) for low pressure air to move over the object while high pressure air slips under. This difference in pressure causes the object to experience lift while moving forward.
500
When designing a vehicle for transportation, what factors might you consider for each zone? give me 1 factor to consider in design for each zone. This is difficult, but you chose 500 hot shot.
Answers will vary for each zone Land: reduce drag, necessary propulsion Sea: buoyancy (it should float), hull design for suspension Air: LIFT! Space: necessary amount of thrust, etc.

Humans create paths and roads to optimize transportation on land, sea, and in the air. Explain why each form of transportation requires planned routes
Air - air traffic control is vital to keep planes from crashing into eachother Land- given such a large number of users, roads and highways are necessary to organize traffic Sea - shipping lanes are required to keep larger ships from accidentally running aground
