Laws of Planetary Motion
This is a set of three laws that were created by Johannes Kepler in 1609 till 1619. Kepler’s three laws of planetary motion states that 1. All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. 2. A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time. 3. The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun. -
Law of Gravity
Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. -
Laws of Motion
This law was published in 1687 by Issac Newton. This law has three parts that consist of Newtons 1-3 . The first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. The second law explains how the velocity of an object changes when it is subjected to an external force. The third laws states that for every action in nature there is an equal and opposite reaction. -
Theory of Evolution
The theory of Evolution by natural selection, first formulated in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. -
Law of thermodynamics
This theory was created by Rudolf Clausius. There are three parts to this theory. The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases. The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. -
Theory of Special Relativity
This theory determines that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels -
Theory of General Relativity
The general theory of relativity is the modern theory of gravitation, proposed in 1915, by Albert Einstein. The general idea of this theory is the principle of general relativity, which states that all observers, regardless of their state of motion, will see the same laws of physics operating in the universe. -
Theory of Plate Tectonics
Wegener made this theory about sea floor spreading and continental drift. Both parts of this theory go together and back each other up. Sea floor spreading proves that continental drift has happened. Continental drift shows that at one point all of the continents were connected but due to sea floor spreading they drifted apart. -
Big Bang Theory
The theory of the Big Bang is a theory of astronomy that states that the universe originated billions of years ago in an explosion from a single point of nearly infinite energy density. -
Law of Cosmic Expansion
This law was published by Edwin Hubble. This law states that the cosmos is always expanding and growing in size. A more in depth explanation is that all galaxies will see other galaxies moving away from them in an expanding universe unless the other galaxies are part of the same gravitationally bound group or cluster of galaxies.
