In common language, the weight of something is typically understood to be the value measured at or near the Earth's surface. Unfortunately the common terms used to describe the weight of an object are units of mass such as kilograms or pounds. For almost all of human history, weight has been measured on the surface of the Earth. Here, the weight is proportional to the mass. Objects which have the same mass have the same weight. An object with the twice the mass of another will also have twice the weight. As a consequence it is common practice to use the two words, mass and weight, as if they mean the same thing and to use kilograms and pounds as the units for both mass and weight. Using the same terms to describe and measure the two different properties has led to confusion between these two properties, mass and weight. Mass and weight are not the same thing.
The unit of weight in the International System of Units is the newton, which is represented by the symbol 'N'.
Other units have been in use in the past but have been abandoned, such as the dyne (the unit of force in the old CGS system) or the kilogram-force, which is the force exerted on a
kilogram of matter by a 'standard' Earth: a body with a mass of 1 kg has a weight of about 9.81 N at sea level.
The weight of an object, or of an amount of matter, is typically measured with an instrument such as a spring scale. The scale includes a spring which provides a force to oppose the gravitational force on the object which is being weighed. The gravitational force pulls down, the spring pushes or pulls upwards. Typically, the scale has a readout which gives not the weight (which is a force) but rather the mass of the object. Spring scales are made with the assumption that they are being used on the surface of the Earth. If a spring scale was taken to the Moon it would give a misleading reading.
A balance style weighing scale is a device that compares the weights of two object in the same gravitational field: it determines whether one object is heavier or lighter than the other.
Weight is not an intrinsic property of matter because the local gravitational field that generates the force called weight is variable in space and time:
Truth
The truth is what is true. It may be everything that is true (reality) or just a part of it (a fact). It may also be a statement that is true: a truth. Things or statements that are not true are untrue or false. True things exist (or have existed); false things do not (or never have).
Aristotle said: "To say of what is that it is not, or of what is not that it is, is false, while to say of what is that it is, and of what is not that it is not, is true." However, a statement may be about how things once were; this would be a true statement if it is clear that it is not a statement about how things are now. Most often, the tense of the verb will indicate this, but there may be other ways in which the statement is qualified: for example, by saying when the statement was true.
Truth is a noun, and the corresponding adjective is true. The word "true" also functions as a noun, a verb and an adverb. The English word "truth" is from Old English "tríewþ, tréowþ, trýwþ", Middle English "trewþe".
Most of the discussion on truth is about one of two things:
Many philosophers have given opinions on these issues.
Something untrue is false. A half truth is something true mixed with something false, or something partly true with key information omitted.
If the things one says are true, then they are speaking the truth, or speaking truly. Saying something that is untrue can be called a lie, if the person who is saying it knows it is untrue. A person who says something untrue is often called a "liar".
"True" is also one of the two basic values of logic. The other such value is usually called "false". In symbols, "true" is written as formula_1, T or 1.
Aristotle was the first to put logic into a formal framework. His version is called propositional logic (see also syllogism and deductive reasoning). Other forms of logic use types of mathematics (mathematical logic) or symbols. Boolean algebra is about things being true and false.
The relationship between verbal claims and external reality is handled by epistemology and the philosophy of science.
Philosophers argue over what makes up truth and how to define and identify truth.
Zimbabwe
The Republic of Zimbabwe is a country in the southern part of the continent of Africa. Its capital city is Harare.
Zimbabwe is surrounded by other countries, and so it has no coast on the sea. This type of country is called "landlocked". The countries that surround Zimbabwe are Zambia, Botswana, South Africa and Mozambique.
Zimbabwe is home to the famous waterfall, Victoria Falls, which are a feature of the river Zambezi and also the Great Zimbabwe, the ancient architectural monument from which the country was named after.
The country is mostly savanna. In the east it is moist and mountainous with tropical evergreen and hardwood forests. Trees include teak and mahogany, knobthorn, msasa and baobab. Among the many flowers and shrubs are hibiscus, spider lily, leonotus, cassia, tree wisteria and dombeya.
There are around 350 species of mammals in Zimbabwe. There are also many snakes and lizards, over 500 bird species, and 131 fish species.
The area that is now Zimbabwe was added to the British Empire around 1890. Zimbabwe is also known by its old name of Rhodesia. In 1965, it became an independent country when Prime Minister Ian Smith announced the Unilateral Declaration of Independence(U.D.I). The government was mostly controlled by the white population, similar to South Africa at the time. African citizens were given full equality in 1980, and the country's name was officially changed to Zimbabwe. Robert Mugabe led the country as the Prime Minister and President for 37 years. Though Mugabe was elected fairly at first, he became a dictator, and had put in place a number of cruel and disastrous laws. On November 21, 2017, Mugabe resigned as President of Zimbabwe.
The country Zimbabwe has a mixture of languages; Shona, Ndebele, Venda, Manyika, Nyanja, Chagani, and a unique-unified Zimbabwean English.
Zimbabwe uses the currencies of several other countries. The government uses the United States dollar. The economy is currently in a bad situation. Foreign currency reserves are at very low levels, and the Zimbabwean Dollar has become very devalued. Just recently, three zeroes were taken off the Zimbabwean dollar (for example, $1,000,000 (one million dollars) would become $1000 (one thousand dollars)). Many observers link this to Mugabe's controversial Land Reform programme.
On November 15, 2017, President Robert Mugabe was placed under house arrest as Zimbabwe's military took control in a coup. On November 21, 2017, Mugabe resigned the Presidency.
Zimbabwe is divided into 8 provinces and 2 cities that are the same as a province.
The largest cities are:
Football is the most popular sport in Zimbabwe. Rugby union and cricket are also popular. Zimbabwe has won eight Olympic medals.
Zimbabwe has also done well in the Commonwealth Games and All-Africa Games. Kirsty Coventry won 11 gold medals in swimming.
Zimbabwe has also been at Wimbledon and the Davis Cup in tennis. Zimbabwe has also done well in golf. Other sports played in Zimbabwe are basketball, volleyball, netball, and water polo, as well as squash, motorsport, martial arts, chess, cycling, polocrosse, kayaking and horse racing. Most of these sports don't have international representatives but instead stay at a junior or national level.
