Quiz Questions
1. Einstein, with this Christian name, received a Nobel Prize in Physics, for his paper ‘On a Heuristic Viewpoint Concerning the Production and Transformation of Light’.
2. This philosopher surmised that the Earth was round, not flat, because during an eclipse, the Earth’s shadow on the Moon was always round.
3. Kepler’s discovery of eliptical orbits, was an advancement in this science, allowing the motions of planets to be predicted.
4. Aristarchus, the Greek astronomer, speculated in the 3rd century BC, that Earth rotates on this, and revolves around the Sun.
5. Galileo’s ‘Dialogues Concerning Two New Sciences’, which sets out the laws of accelerated motion governing falling what, is an important contribution to modern physics.
6. This Polish priest was convinced of the heliocentric model of the universe, but proposed it only as theory, because he was afraid the church would label him as a heretic.
7. In celestial navigation, astronomers measure longitude in these, and each 15 of these is equal to one hour, therefore 360 of them equals 24 hours.
8. Aristotle and Ptolomy held the belief that the universe was geocentric, that the Sun revolved around this planet.
9.Kepler’s first law states that the planets move in this type of orbit around the Sun, therefore being closer to the Sun at certain times of the year, than at other times.
10. He was sentenced to life imprisonment, but never officially condemned, for stating that the Earth revolved around the Sun, in defiance of the Church’s 1616 edict.
11. Although Aristarchus proposed it before 230 BC, Copernicus was the first credited with the conclusion, that this type of universe existed.
12. This unstable scientific intellect, ……Newton was considered the father of the study of infinitesimal calculus, mechanics, planetary motion, and the theory of light and colour.
13. Since Einstein, Stephen Hawking is considered the most brilliant in this field.
14. Kepler’s third law of this motion states that the square of the number of years of a planet’s orbital period, is equal to the cube of that planet’s average distance from the Sun.
15. This is the third one of motion: ‘ To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.’
16. Francesco Maria Grimaldi’s experiment into the splitting of this, led to Newton’s experiments of passing it through a prism, and splitting the beam into the spectrum.
17. Kepler, using Brahe’s accurate calculaions of the position of this planet, theorised that the orbit was elliptical, in contradiction to what astonomers believed at the time.
18. From his observations, through his telescope, Galileo concluded that this satellite’s surface consisted of valleys, plains, and mountains, similar to the surface of the Earth.
19. Sir Isaac Newton was famous for formulating gravitational force and defining the laws of this, and attraction, in his work: ‘Mathematical Principles of Natural Phylosophy (Phylosophiae Naturalis Principia Mathematica), known as Principia.
20. Kepler’s, the most recent one in our galaxy, to have been observed by the naked eye, was also recorded by the Chinese and Koreans.
21. In astronomy, in the law of the ……, the number of these gives you the scale, making it possible to convert the whole solar system into sound, demonstrating relationships.
22. This is the gravitationally elliptical path of an object around a point in space, such as the planets and many satellites in our solar system.
23. This astromomer developed a model that predicted the movement of the Sun, Moon, planets, and stars, and that these objects moved at constant speeds in circular orbits.
24. Several scientists contributed to this mechanics, where objects exist in uncertaintity; having as much chance of being at point A, as of being at point B and so on.
25. A heliocentric universe is the model of the solar system, in which the Earth and planets do this around the Sun.
26. Aristotle believed that Earth, rather than a flat plane, was this.
27. Galileo noted this planet as being oblong, as his telescope was unable to detect it’s rings.
28. Einstein’s relativity what, in part, states that the inertia mass of a body increases with the energy it contains.
