Science – For Your Information http://www.robertmbarker.com A blog about stuff you never knew. Tue, 23 Apr 2013 20:01:42 +0000 en-US hourly 1 https://wordpress.org/?v=4.4.11 Newton’s Three Laws of Motion and what they mean in simpler terms. http://www.robertmbarker.com/newtons-three-laws-of-motion-and-what-they-mean-in-simpler-terms/ Wed, 10 Apr 2013 13:59:57 +0000 http://www.robertmbarker.com/?p=23 Continue reading ]]> First Law: Every object continues in a state of rest or in a continuous motion in a straight line, except in so far as it is compelled to change that by forces exerted upon it.

What that means: If you shoot an arrow at a target, it will keep going straight without going down or up unless it is affected by gravity (or your friend Jim) which it will be. Gravity is the force being exerted upon the arrow, pulling it down to the ground.

Second Law: Acceleration is produced when a force is acts on a mass. The greater the mass of the object being accelerated, the greater the force needed to accelerate the mass.

What it means: If you were pulling a fat guy up onto the top of a cliff from the bottom, you would need to pull harder than if you were pulling a skinny guy onto the top of a cliff.

Third Law: Objects interact such that for every force exerted on one, there is an equal and oppositely directed force on the other.

What it means: Say you were sitting in a chair with wheels on the bottom next to a wall. If you push against the wall, you will be pushed backwards. The equal force is where you are pushed back with the force that you pushed on the wall. The opposite force is where you were pushed away from the wall.

How flying car air traffic could work. http://www.robertmbarker.com/how-flying-car-air-traffic-could-work/ Wed, 03 Apr 2013 19:20:32 +0000 http://www.robertmbarker.com/?p=19 Continue reading ]]> In my last post, I talked about flying cars and how they are becoming a reality. Now, let’s jump forward in time a few years, to where we have flying cars.

In my own little wishful-thinking future, we have flying cars with wings that need runways to takeoff. We have been using the roads for takeoff for a few days now. But we have a problem.

Unlike normal roads, which have one side of the street going one direction and the other side doing the opposite, we can’t put lines in the sky. We also can’t put stoplights and speed limit signs in mid-air either.

Without these things, people would be crashing into one another, and there could possibly be an average of 20,000 deaths per day in the US (There’s approximately 13,000 deaths every day as of now).

Then we have another problem: landing and taking off. There’s a reason  runways are so long, it’s because it takes about 4 or 5 minutes to slow down.

But I have a solution to all of this: autopilot.

Autopiloted flying cars could reinvent traveling. What you would do is get in your flying car, enter in the address of the person you are visiting, and sit back and do the rest.

The only problem is that all the other flying cars would have to be hooked up to the same system, so that your flying car would know where all the other flying cars are, and be able to avoid them.

Taking off and landing would be easier, too. The autopilot would find the nearest flat road, land there, and drive the rest of the way to your friend’s house.

Why don’t we have flying cars? http://www.robertmbarker.com/why-dont-we-have-flying-cars/ Wed, 27 Mar 2013 17:24:57 +0000 http://www.robertmbarker.com/?p=14 Continue reading ]]> Flying cars, the worldwide dream of what the future will hold. But we have been wishing for these things for at least 50 years, so why doesn’t everyone have one?

Many people think that it’s because the technology is far beyond our reach, but the truth is, people have been testing flying cars for the past ten years or so.

But most of the flying cars (or drivable aircrafts, as they call them) require a runway to take off, and that’s not the easiest thing to find in a traffic jam.

Thankfully, people have begun to create vehicles that take off and land vertically, making a runway unnecessary.

Then there is the government’s response to flying car. They’ve spent hundreds of thousands of dollars on roads, they aren’t about to throw them away just because we don’t need them.

That’s why I think, if we do end up only having flying cars that require runways, that roads could be of use for taking off.

Therefore, the government would be happy that they aren’t losing money and we’d be happy we have flying cars.
