Constant Acceleration



Technofiction Writing Tips - Part 2 of 4 - Space Travel Without Warp Drive

... shooting people into space with cannons was in 1900. But it doesn't violate laws of physics the way warp drive does.) If you're not going to use constant acceleration, if you're sticking with boost-and-coast, the technology that is real today, plan on using some form of suspended animation or grow-when-you-arrive. An interstellar trip is going to take centuries to millennia. o If your journey is constant acceleration, the people on the space craft will spend most of the journey traveling close to the speed of light -- relativistic speeds. This means that travelers' clocks will be ticking ... . In STL stories that's not true: star systems are really far apart! It takes years to decades to go from one to another. So what changes in your story telling? Here are a few basic changes: o The fastest way to travel between stars with STL drives is a constant acceleration drive -- basically the propulsion stays running for the whole trip. During the first half of the journey it accelerates and during the second half it brakes, so you arrive at the destination standing still, not zooming by at something close to the speed of light. (Note: we still don't ...

Tips to Increase Swing Speed in Golf

... before swinging it back to the top. Repeat this a few times before you launch into the forward swing. Give special attention to the follow through. Remember to maintain the correct position of your body, arms, shoulders and legs at all times. Do this in front of a mirror. Maintaining constant acceleration, keeping the face of your club squared throughout impact, using the muscles in the legs and trunk rather than in the arms and hands are all effective ways to increase the speed of your golf swing. Work with your trainer and get him to show you various ways to increase ...

Fun With Physics: Can You Turn Into A Black Hole?

... constantly ever increasing acceleration (probably interpreted as a source of artificial gravity according to Einstein's Principle of Equivalence between acceleration and gravity), just like (even with your eyes closed) you know acceleration is happening when the car you're in turns a corner because you are pushed to one side of the vehicle, or when you are pushed into the back of your seat when the aircraft starts its takeoff run. You could interpret the pushing as a form of artificial gravity. That's in contrast to feeling no extra forces when the car or plane is moving at constant velocity in a ... form of artificial gravity. That's in contrast to feeling no extra forces when the car or plane is moving at constant velocity in a straight line. If your eyes are closed, you might swear you're not moving at all. Additionally, you (the pilot), if you are carrying an onboard fuel supply, would notice that your fuel supply was decreasing at an ever increasing rate as increasing fuel units are needed to keep up the extra and ever increasing acceleration to push the ever increasing massiveness of you and your ship towards light speed. If it takes one unit of fuel ...

What Would Physically Happen to Your Body If You Reached the Speed of Light

Clearly to get to an acceleration of a, the force needed is proportional to the mass of the object. Greater the mass; the greater the force needed. If such an object did reach 99.99999...the speed of ... and Bob fire a laser beam in their direction of motion. Both beams travel at the same speed of light. Einstein's leap of faith was to realize that the speed of light is a constant in all inertial (non-accelerating) frames of reference. However time is not a constant in different inertial frames, and ...

BMW E61 535d Sport Touring Review

Having lived and travelled extensively in Germany, the car is fantastic at autobahn speeds and is as steady ... learned and once you have got used to it, it can be done without thinking about it. The second issue is that in top gear at around 1900 RPM with a constant load on the throttle, there appears to be what seems like a flat spot. Whilst it doesn't lose power, any small depression of the pedal has no effect and ...

How to Combat Rising Gas Prices: Make Your Fuel Last Longer

... off with the breeze as often as possible, especially if you're driving on side roads. Drive steadily. Constantly speeding up, braking and speeding up again uses up a lot of fuel. However, driving at a steady, constant pace can help each tank of gas last longer. Accelerate easily. The faster you accelerate, the more gas your car uses. If you let the acceleration occur at a more natural pace (i.e. not letting your engine go "vroooooooom"), you will save significant amounts of fuel on every tank. Each of these steps is simple to take, and the benefits are clear. By ... save money in other areas of their budget. Although there's nothing you can do to bring these increasing gas prices down, there are several things you can do to improve your car's fuel economy. Take the following steps to help your gas last longer: Drive more efficiently. Quick acceleration and braking as well as speeding can reduce fuel economy. In fact, FuelEconomy.gov states that aggressive driving can reduce gas mileage by 33 percent. Take excess weight from the car. If you have golf clubs, toolboxes, or any other items that add weight to your car, take them out ...

The Ten Cosmological Fallacies

... a red tie to work, and has a wife and two kids, that's pure coincidence and no explanation is required. Now the "Cosmic Coincidence" relates to the fact that the cosmological constant or dark energy or the vacuum energy responsible for the acceleration of the already existing expansion of our observable universe happens to be roughly equivalent in strength to the Universe's matter density. The former is forever constant despite the expansion while the latter is forever decreasing as matter (gravity) is being diluted due to that same expansion. Of course the two lines have to cross at some point in ... may not be micro (quantum realm) objects either. Firstly, it's common sense that a singularity can not have zero volume and infinite density. Therefore, a singularity must have a finite volume and a finite density. As one adds more and more stuff to a singularity, the volume may remain constant while the density increases. But, because density can not hit infinity, it must have a limit. When that limit is reached, the volume of the singularity must increase. It follows therefore that the size of a singularity will eventually reach macro dimensions and fall out of the realm of quantum ...

Creativity: The Uncertainty And Insanity Involved In It

... it's constant, why do we keep fighting it? Why don't we more readily accept it? Take, for instance, how vigilantly we fight against Niagara Falls leaving Niagara, New York. Niagara Falls, a beautiful, spectacular waterfall in the United States, is one that we humans manipulate so as to control its rate of change. We apparently don't like the uncertainty of where it may end up if left to its own devices. Waterfalls are actually a temporary geological phenomena; temporary since the pounding of the water at the base causes erosion at the bottom, while the acceleration of water over ... is to stifle life. It's an insane thing to do. To dam the flow of our creativity is to assure that we stay in the same place, just like we are trying to keep Niagara Falls stuck in place. And, yet we know with some certainty that the only constant is change. We should always be changing. It's good for us. There is stuff in the unconscious that looks insane, but no more insane than what we see in the world around us. This is classic repression and projection from the world of psychology. Projection is a psychological defense ...

... light into its spectrum and back into white light, concluding light to consist of tiny particles. In Principia, Newton entered F = ma (Force equals mass times acceleration), now considered the most useful physical law ever written. Newton assumed the cosmological system to prove God existence and thought science a form of worship. Brennan ... two different words for the same thing. Einstein forever changed the way intellect must intercept the appearance of time, space, and matter. Add to this his Cosmological Constant, later rejected, later still revived: a factor to account the invisible force holding our universe in space continuum. Contemporaneous with Albert Einstein, Max Karl Ernest Ludwig ...

How to Get Better Mileage Out of Your Vehicle

... spark plug causes misfiring which wastes fuel. Replace your spark plugs at regular intervals according to your vehicle manufacturer's recommendations. Watch your speed As your speed increases over 60 mph, mileage begins to drop rapidly. To maintain constant speed on the highway, cruise control is recommended. Watch aggressive driving It's been stated that aggressive driving can cost up to 33% in fuel mileage. General habits of acceleration and deceleration can have the biggest impact on your mileage. Most people don't realize that it can be the little things that can add up to big savings at the gas pump.

More Ways To Survive The Coming Gasoline Crunch

... $5 a gallon, every little bit will help. Here's a novel idea: forego use of a car altogether. Using a bicycle or motorcycle can get a lot of miles out of very little gas. Opt for smooth driving. Cars use the most gas during acceleration, and the least while actually cruising at a given speed. Constant breaking and speeding back up wrecks your mileage. Learn how to pace yourself, accelerate to your desired speed, then try to keep it there with a minimum of stutterstops. Air conditioning works your cars' systems harder. Don't run the AC whenever possible. Rolling down ...

Pressure Basics - Air and Hydrostatic

... sufficient pressure when consumers turn on their taps. But hydrostatic pressure is fundamentally different in that it's "natural" pressure as opposed to mechanized pressure. Assuming that the fluid is incompressible - water compresses 46.4 ppm per atmosphere of pressure - maintaining a constant density throughout the fluid, and that the column height is such that any variation of the gravitational acceleration is negligible, the formula can be expressed as pressure = pgh, with p being fluid density, g being the gravity of Earth, and h being the height of the water column. One thing to keep in mind - and something that is often ...
