Science Revision Notes Chemistry Atoms are the smallest particle of a particular element. Molecules are particles that contain 2 or more atoms joined together by chemical bonds. Elements are substances that are made up of only one type of atom. Compounds are substances form when two or more elements are joined chemically. Metals are solid at room temperature‚ with the exception of mercury. Metals are good conductors of electricity and heat. Metals can usually be melted at high temperatures. Non-metals

PHYSICS UNIT 2 Physics P2 for GCSE Additional Science or GCSE Physics AQA GCSE Science PHYSICS 2 Unit P2.1 Forces and their effects Appreciate that forces can cause changes to the shape or motion of an object. Not only can objects can move in a straight line at a constant speed but they can also change their speed and/ or direction (accelerate or decelerate). Be able to use/produce graphs can help us to describe the movement of an object. These may be distance-time graphs or velocity-time graphs

Aphelion: (opposite of perihelion) the point in its orbit where a planet is farthest from the Sun; when referring to objects orbiting the Earth the term apogee is used; the term apoapsis is used for orbits around other bodies. 2. Astronomical unit – (1 AU = 149‚597‚870.691 kilometers) An Astronomical Unit is approximately the mean distance between the Earth and the Sun. It is a derived constant and used to indicate distances within the solar system. Its formal definition is the radius of an

Physics (from Greek)‚ i.e. "knowledge‚ science of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is the field of science that studies the physical world.

What is Physics? Physics is a field of science that shows the interaction between matter and energy. It shows physical processes that help us understand better how our universe behaves. Physics also use scientific method that formulates and tests hypothesis which are based on observations and comprehensions. What are the different fields under Physics? PHYSICS PHYSICS dealing with physical processes and their relations in the science of physical chemistry. dealing

Some may ask what the Anthropocene is. Before this moment‚ I had never heard of it. The Anthropocene is very important because it is able to show just how humans have impacted the earth‚ and how we have changed it. As humans‚ we are pushing the wildlife into smaller areas as we create new homes‚ and disrupt their habitat. The earth is facing its sixth extinction‚ and studies show that humans are to blame. This does not mean every single animal species has suffered a loss of 25%. Some are impacted

1 IDENTIFY THE DIFFERENT ROLES IN THE VETERINARY FIELD AND RECOGNIZE THEIR IMPORTANCE WITHIN THE PRACTICE In the veterinary field there are four main and important roles that work together to create a well-oiled team to ensure that their day-to-day jobs run smoothly. Firstly‚ the most important role is the Veterinary Surgeon. Veterinary Surgeons are responsible for the medical and surgical treatment for the animals. They also work to try to prevent disease in animals and the spread of disease. Secondly

Progression of Chemistry The birth of the modern atomic theory. In 1750‚ Rudjer Boscovich‚ a scientist born in what is now Croatia‚ suggested the theory that atoms were "uncuttable" might have been wrong. Boscovich thought that atoms contain smaller parts‚ which in turn contain still smaller parts‚ and so forth down to the fundamental building blocks of matter. He felt that these building blocks must be geometric points with no size at all. Today‚ most atomic physicists accept a modern form of this idea
