Force is defined as a push or a pull acting on an object. Examples of forces include friction and gravity. Both are covered in detail later in this chapter. Another example of force is applied force. It occurs when a person or thing applies force to an object, like the girl pushing the swing in Figure 13.1. The force of the push causes the swing to move. Force is a vector because it has both size and direction. For example, the girl in Figure 13.1 is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push. Thats the size, or strength, of the force. Like other vectors, forces can be represented with arrows. Figure 13.2 shows some examples. The length of each arrow represents the strength of the force, and the way the arrow points represents the direction of the force. How could you use an arrow to represent the girls push on the swing in Figure 13.1? The SI unit of force is the newton (N). One newton is the amount of force that causes a mass of 1 kilogram to accelerate at 1 m/s2 . Thus, the newton can also be expressed as kgm/s2 . The newton was named for the scientist Sir Isaac Newton, who is famous for his law of gravity. Youll learn more about Sir Isaac Newton later in the chapter. More than one force may act on an object at the same time. In fact, just about all objects on Earth have at least two forces acting on them at all times. One force is gravity, which pulls objects down toward the center of Earth. The other force is an upward force that may be provided by the ground or other surface. Consider the example in Figure 13.3. A book is resting on a table. Gravity pulls the book downward with a force of 20 newtons. At the same time, the table pushes the book upward with a force of 20 newtons. The combined forces acting on the book or any other object are called the net force. This is the overall force acting on an object that takes into account all of the individual forces acting on the object. You can learn more about the concept of net force at this URL: . When two forces act on an object in opposite directions, like the book on the table, the net force is equal to the difference between the two forces. In other words, one force is subtracted from the other to calculate the net force. If the opposing forces are equal in strength, the net force is zero. Thats what happens with the book on the table. The upward force minus the downward force equals zero (20 N up - 20 N down = 0 N). Because the forces on the book are balanced, the book remains on the table and doesnt move. In addition to these downward and upward forces, which generally cancel each other out, forces may push or pull an object in other directions. Look at the dogs playing tug-of-war in Figure 13.4. One dog is pulling on the rope with a force of 10 newtons to the left. The other dog is pulling on the rope with a force of 12 newtons to the right. These opposing forces are not equal in strength, so they are unbalanced. When opposing forces are unbalanced, the net force is greater than zero. The net force on the rope is 2 newtons to the right, so the rope will move to the right. Two forces may act on an object in the same direction. You can see an example of this in Figure 13.5. After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces

Ex Output:
force that a person or thing exerts on to an object

The following five destination shall never be missed *Blue Lagoon : Blue Lagoon geothermal spa is one of the most visited attractions in Iceland. The warm waters are rich in minerals and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases. The water temperature in the bathing and swimming area of the Lagoon averages 37degC - 39degC(99F -102F). The Blue Lagoon also operates a research and development facility to help find cures for skin diseases using the mineral-rich water. *Budapest: Budapest holds the title "City of Spas" since the year 1934, as it has more hot and medicinal water springs than any other capital city in the world. There are 118 springs in Budapest, providing over 70 million liters of hot water a day. The temperature of the waters is between 22degC and 40degC. *El Tatio: El Tatio is a geyser field located within the Andes Mountains of northern Chile at 4,320 meters above sea level. With over 80 active geysers, the site is the largest geyser field in the southern hemisphere and the third largest in the world. It is a major tourist attraction in Chile and is among the highest-elevation geyser fields in the world. The temperature of the waters goes between 70degC and 85degC. *Hokkaido: Visitors to the Japanese island of Hokkaido have plenty of options. These range from top resorts with thermal baths like the Spa Resort Hawaiians to small traditional inns that have their own small hot pools with water temperature comfortable to skin. Some bathing spots are outdoors and are not associated with any spa or inn. The classic forest and mountain landscapes of this nature-rich island make it a great choice for those seeking a science setting for their baths.

Ex Output:
Which site of the spring has the greatest gap of water temperature?

A study suggests that although most students at UK universities are happy with their courses, dissatisfaction has grown as fees rise.The study highlights a big variation in teaching time, and lists different ideas about the value of getting university degrees. Katharine Collins, a second-year college student The course has been very interesting, but I was expecting a little more one-to-one time with my teacher. We do about four assignments each term, each of which is about 3,000 words.However, sometimes they are not that helpful.We hope to be given the right to write feedback after every assignment, but we had no feedback at all throughout the first year.We are given grades about three weeks after we hand the assignments in.There is no feedback on where we have gone wrong or how we might improve. Lee Millington, a creative-writing student I choose the courses because of its reputation.There is a lack of one-to-one teaching.I would like personalized feedback from an expert in my field of writing.Some of the lectures have been quite helpful but they try to use too many different styles of writing.For example, if you want to be a poet, you might find that the lectures focus too much on novels. I think there is too much attention paid to sharing our work in workshops and giving each other feedback.I think there should be more time given to actual teaching, rather than to feedback from people who are at a similar level to me. Reporters from Hounsdown Secondary School, Ella, 16 When I work independently, I feel I have more freedom to develop my ideas and come up with more original viewpoints.The price of university will still be worth it to get the qualifications necessary for better jobs. Tyier, 16 Although the cost of university is very high now, I think university is required for gaining a good and well-paid job. Agencies
