Q: Kinetic energy is the amount of energy in the form of motion. Like any unit of energy, it can be express in units of Joules. Kinetic energy is equivalent to the amount of work done to accelerate a stationary object to a certain speed. Once it has reached that speed, the object retains that amount of kinetic energy until that energy transforms into heat (from friction), gravitational potential energy (from moving against gravity), or other types of energy. For example, we can measure the kinetic energy of a bicycle & bicyclist. Let's say the cyclist has a mass of 50 kg, and the cycle has a mass of 20 kg, for a total mass m of 70 kg. We can now treat them as one 70 kg object, since they'll be traveling together at the same speed. . If you already know the bicyclist's speed or velocity, just write it down and move on. If you need to calculate it yourself, use one of these methods below. Note that we care about the speed, not the velocity (which is speed in a certain direction), even though the abbreviation v is often used. Ignore any turns the bicyclist makes and pretend all distance traveled is one straight line.  If the bicyclist moved at a constant rate (didn't accelerate), measure the distance the bicyclist traveled in meters, and divide it by the number of seconds it took to move that distance. This will give you the average speed, which in this scenario is the same as the speed at any given moment. If the bicyclist is accelerating at constant acceleration and doesn't change direction, calculate his speed at time t with the formula "speed at time t = (acceleration)(t) + initial speed. Use seconds to measure time, meters/second to measure speed, and m/s2 to measure acceleration. Kinetic energy = (1/2)mv2. For instance, if the bicyclist is traveling at 15 m/s, its kinetic energy K = (1/2)(70 kg)(15 m/s)2 = (1/2)(70 kg)(15 m/s)(15 m/s) = 7875 kgm2/s2 = 7875 newton meters = 7875 joules. The kinetic energy formula can be derived from the definition of work, W = FΔs, and the kinematic equation v2 = v02 + 2aΔs. Δs refers to "change in position," or the amount of distance traveled.
A: Understand kinetic energy. Find the mass of the object. Calculate speed Enter these numbers into the following formula.

Article: Lucid dreams, and vivid dreams in general, almost always occur during the REM stage of sleep. The first REM phase typically occurs ninety minutes after you first fall asleep, with additional phases roughly every ninety minutes afterward. The goal of this method is to wake up during a REM phase, then fall back asleep and continue the dream aware that you are dreaming. You won't be able to time your phases exactly unless you visit a sleep lab or have a very dedicated night owl watching your eyelids all night. More realistically, just keep repeating the method below until you catch yourself in REM phase. . There are many ways to increase the amount of REM sleep you get, as described in the linked article. One of the most effective, and the one that causes REM sleep to appear at regular times, is to stick to a daily sleep schedule and to sleep long enough that you wake up well-rested. This can be difficult to balance with the step below, which interrupts your sleep in the middle of the night. If you have trouble falling back asleep, try a different method instead, or limit your attempts to once or twice a week. Set one alarm to go off either 4.5, 6, or 7 hours after the time you fall asleep. You're more likely to be in REM sleep during these times, although it's difficult to predict in advance. The six or seven hour times are the most likely to work, because later REM phases last longer, and are more likely to contain vivid or lucid dreams. Write down your dream if you were having one, make yourself a snack, or just get up and walk around for a while. Your goal is to get your conscious mind active and alert, while your body is still full of sleep hormones. One study shows that staying awake for somewhere between 30 and 60 minutes gives the highest chance of a lucid dream. Close your eyes and fall asleep again. If you remember the dream you were having, recall it and fall back asleep, imagining yourself continuing the dream. Even if this takes quite a while to happen, you've got a decent chance at a lucid dream. If your mind wanders while trying to "catch" the dream, or if you don't remember the dream at all, instead try focusing on the movement of your fingers. Use a pattern of small movements, such as "index finger up, middle finger down, middle finger up, index finger down." Repeat this rhythmic movement until you fall asleep.
Question: What is a summary of what this article is about?
Know when lucid dreams most commonly occur. Encourage your body to get more REM sleep Wake up in the middle of the night. Stay awake for a while. Concentrate on the dream and fall asleep again. Try other concentration techniques.

Q: Similar with any semi-permanent buildings. It is not just a matter of permission for more pitches – it is also a matter of what obligations you may have in terms of upgrading existing infrastructure, electricity supply, water supply, sewerage, access, security, health and safety. For instance, the electrical supply may only be sufficient for the electric current demand of the existing number of pitches so existing cable work may need replacing. Is the capacity sufficient for current use and any expansion plans? Has the system been inspected by the relevant state or local authorities - have they issued any demands for improvements and, if so, how long would you have to comply and how much would it cost? Most will have a website or year book; check if to see if the campsite is listed and if so, what comments and ratings are given. Most large camping organisations also have inspectors who visit sites – find out what they are looking for when they rate a campsite. For instance, a certain governing body in Europe stipulates a minimum shower cubicle width as a condition for a certain star rating - if cubicles have already been built but are too small, then obtaining higher star ratings may prove expensive. You could choose to view the inspector's demands as a hurdle to jump but actually he only represents the wishes of the majority of campers in the organisation he represents, so really his comments should be seen as valuable commercial advice - ignore the wishes of your campers at your peril!
A:
Consider whether permits have been obtained for the number of spaces or pitches already operated. If you plan to expand the campsite, talk to the relevant authorities before purchase. Remember that sewerage does not travel uphill, at least not without specialist sewerage pumps, so you need to consider the existing layout when considering expanding into areas of differing elevations.
