• the shape of the Earth - oblate spheroid
• He believed that the Sun, the moon, the five known planets and the stars were attached to these spheres which carried the heavenly bodies while they revolved around the stationary Earth. - Eudoxus
• He measured the Earth’s circumference with a stick, a knowledge of the distance from Alexandria to Syene and geometry. - Eratosthenes
• He believed that the earth was the center of the universe and his Ptolemic Model claimed that the planets moved in a complicated system of circles. - Ptolemy
• An ancient Greek philosopher who included the following in his argument supporting a spherical Earth: position of the North Star, the shape of the moon and the sun and ships disappearing over the horizon. - Aristotle
• A phenomena when one celestial body cross between the sun and another celestial body. A shadow is cast at the second celestial body. - Eclipses
• A phenomena that occurs when the Moon is in between the Sun and the Earth and the moon partially or completely blocks out the sun. - Solar Eclipse
• A phenomena that occurs when the Earth casts its shadow on the moon when the Earth is between the Sun and the Moon. - Lunar Eclipse
• A phenomena that result of the changing relative position of Earth, the Moon, and the Sun as the Earth-Moon system moves around the Sun. - Moon Phases
• four (4) major phases of the moon - new moon, first quarter, full moon and last quarter
• Apparent movement of stars and other celestial bodies around the earth as a direct effect of the Earth’s rotation on its axis. - Diurnal Motion
• It is a motion of the Earth, and its orbit around the Sun (it takes around 365 days for the Earth to complete 1 orbit). - Annual Motion
• He used in telescope to make extensive astronomical observations and determine that the planets orbit the sun in elliptical orbits. - Tycho Brahe
• He worked under Brahe and tasked to investigate the path of Mars’ orbit under Brahe’s research. - Kepler
• The point at which an orbit comes closest to the Sun is called perihelion
• The point at which an orbit is farthest from the Sun is called aphelion
• A theory that the Earth is the center of the universe, with the sun and planets revolving around it. - Geocentric Model
• A theory that the sun is at the center of the universe and we move around it along with all the other planets. - Heliocentric Model
• States that an imaginary line between the Sun and a planet moves over equal areas of the ellipse during equal time intervals. - Kepler's second law of planetary motion
• What model describes perfect geometrical spheres with attached celestial bodies orbiting around a fixed Earth in perfect circles. - Geocentric model
• A motion arising from the nature of an object. This motion does not require an external cause in order to occur. - Natural Motion
• Motion contrary to the nature of the object and requires an external force in order to occur. - Violent Motion
• He believes that force is necessary to produce motion. - Aristotle
• He believed that the prime mover of motion is God, and the sphere of firmament (ether) is heaven and his idea is recognized by the Roman Catholic Church many years. - Aristotle
• He is the Father of Modern Science and Scientific Method and completely opposed Aristotelian concept of motion - Galilei
• He believe about acceleration is dependent on mass (heavier objects will fall faster than lighter object). - Aristotle
• He believe that the objects speed does not depend on mass. Acceleration depend on time of fall. - Galilei
• It is an object that is falling under the sole influence of gravity.  - Free Fall
• It can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. - Speed
• He is the Father of physics that made significant contributions to the field of physics and develop the three laws of motion. - Newton
•  called the Law of Inertia - first law
• the objects at rest tends to stay at rest and objects in motion tend to stay in motion unless acted upon by an unbalanced force - law of inertia
• states that force equals mass times acceleration - law of acceleration
• Law of motion states that for every action, there is an opposite and equal reaction. - law of interaction
• ANTE MERIDIAN stands for - Before meridian
• "umbra" - complete/full shadow
•  the closest star in the solar system - sun
• Annular - ring shaped
• How many phases of the moon do we have? - 8
• POST MERIDIAN - after midday
