INPUT ARTICLE: Article: You don't have to have cable any more if you don't want to. Many popular TV shows and movies can be watched through services like Netflix or Hulu, which can even stream right to your TV. These usually cost money, but it's much, much cheaper than paying for cable. Youtube carries all sorts of different video content. You can watch funny clips, family movies, full TV shows, full movies, clips of either of those things, or even just do things like listen to songs. You can play games online (or even gamble!). Websites like Games.com offer lots of free, classic games that you can play. Another option are games like fantasy football: a number of league are available online that you can enjoy for free. If you loved reading comics when they were in the newspaper, you can read many of those same comics online. Try a search for your favorite comic...you might be surprised!   Read Garfield here.  Read Family Circus here. Find new comics. There are lots of new comics that have never been up in the newspapers but can be read for free online. These are called webcomics, and cover a huge range of topics. You can also listen to music online. There are many free websites that let you listen to music that you like. Pandora is a free internet radio that lets you choose what kind of music to listen to.  Slacker.com is similar to a satellite radio service with a wide variety of music of all genres. You can also try to bring up specific songs or artists using websites like YouTube.

SUMMARY: Watch television and movies. Watch YouTube. Play games. Read comics. Listen to music.

INPUT ARTICLE: Article: To start, it's important to first be able to identify both the direction the object is moving in and the direction from which force is being applied. Keep in mind that objects don't always move in line with the force being applied to them — for instance, if you pull a small wagon by its handle, you're applying a diagonal force (assuming you're taller than the wagon) to move it forward. In this section, however, we'll deal with situations in which the force and the object's displacement do have the same direction. For information on how to find the work when these things don't have the same direction, see below. To make this process easy to understand, let's follow along with an example problem. Say that a toy train car is being pulled directly forward by the train in front of it. In this case, both the force vector and the direction of the train's motion point the same way — forward. In the next few steps, we'll use this information to help find the work done on the object. The first variable we need for the work formula, D, or displacement, is usually easy to find. Displacement is simply the distance that the force has caused the object to move from its starting position. In academic problems, this information is usually either given to or is possible to deduce from other information in the problem. In the real world, all you have to do to find displacement is measure the distance the object travels.  Note that measures of distance must be in meters for the work formula. In our toy train example, let's say that we're finding the work performed on the train as it travels along the track. If it starts at a certain point and ends at a spot about 2 meters (6.6 ft) up the track, we can use 2 meters (6.6 ft) for our "D" value in the formula. Next, find the magnitude of the force being used to move the object. This is a measure of the "strength" of the force — the bigger its magnitude, the harder it pushes the object and the quicker it accelerates. If the force's magnitude isn't provided, it can be derived from the mass and acceleration of the moving (assuming that there aren't other conflicting forces acting on it) with the formula F = M × A.  Note that measures of force must be in newtons for the work formula. In our example, let's say that we don't know the magnitude of the force. However, let's say that we do know that the toy train has a mass of 0.5 kilograms and that the force is causing it to accelerate at a rate of 0.7 meters/second2. In this case, we can find the magnitude by multiplying M × A = 0.5 × 0.7 = 0.35 Newtons. Once you know the magnitude of the force acting on your object and the distance it's been moved, the rest is easy. Simply multiply these two values by each other to get your value for work.  It's time to solve our example problem. With a value for force of 0.35 Newtons and a value for displacement of 2 meters (6.6 ft), our answer is a single multiplication problem away: 0.35 × 2 = 0.7 joules. You may have noticed that, in the formula provided in the intro, there's an additional piece to the formula: Cosine(θ). As discussed above, in this example, the force and the direction of motion are in the same direction. This means the angle between them is 0o. Since Cosine(0) = 1, we don't need to include it — we're just multiplying by 1. In physics, values for work (and several other quantities) are almost always given in a unit of measurement called joules. One joule is defined as one newton of force exerted over one meter, or, in other words, one newton × meter. This makes sense — since you're multiplying distance times force, it's logical that the answer that you get would have a unit of measurement equal to multiplying the units of your force and distance quantities. Note that joules also has an alternate definition — one watt of power radiated over one second. See below for a more detailed discussion of power and its relationship to work.

SUMMARY:
Find the direction of the force vector and the direction of motion. Find the displacement of your object. Find the force on the object. Multiply Force × Distance. Label your answer in joules.
