Physical Science: Moon & Eclipse Situational Problems

Moon and Eclipses I. Answer all questions briefly and conciselyProblem # 1Nonong went outside from his house to see the spectacular view of the sky at midnight. He noticed that the shape of the moon is crescent like structure. After two days, at the same time, he observed that there is no appearance of the moon in the sky.(a) Identify the two phases of the moon mentioned in the situation(b) Explain briefly the concept behind the two days delay of changing from one phase to another of the moon.(c) How long does it take for the moon to complete its lunar cycle and why?Problem # 2The three heavenly bodies were aligned to each other in a straight line. The Sun, Moon and the Earth have been designated as variables S, M and E. There are distances among these bodies namely D1 (the distance from S to the center) and D2 (the distance from the center to the third body). There are also forces acted among these bodies namely G1 (the force from S to the center), G2 (the force from the center to the third body) and G3 (the force from S to the third body).Figure 2.1 G1 G2 D1 D2 G3Figure 2.2 G1 G2 D1 D2 G3(a) Positiona.1 What do you call the position of these two figures when these three bodies fall in a straight path?a.2 What is the term coined when E is between S and M?a.3 What is the term coined when M is between S and E?(b) Distanceb.1 The distance between E and M in figure 2.1 is D2, what do you call this position of M with respect to E?b.2 The distance between M and E in figure 2.2 is also D2, what do you call this position of M with respect to E?(c) Forcesc.1 What are the two factors that determine the amount of force that the object can exert?c.2 Among these three bodies, Which one exert greatest force? Why? c.3 Compare the force G3 and G2, which one have greater impact on Earth? Why?(d) Shadowd.1 What do you call the darkest shadow occur when these three bodies aligned to each other?d.2 What do you call the lightest shadow occur when these three bodies aligned to each other?Problem # 3The Earth, Sun and Moon has been assigned as E, S and M.The bodies S and M is perpendicular with respect to EFigure 3.1 The bodies S, E and M were aligned to each other Figure 3.2 (a) Identify the type of tide and state the impact of the positions of the three bodies on body E in figure 3.1. (b) Identify the type of tide and state the impact of the positions of the three bodies on body E in figure 3.2.(c)How long does it take the shifting from high to low tide and vice versa and why?Problem # 4 Sunlight (a).Write the names of each phases of the moon on the space provided and shade each circle to indicate each shape.1.2.3.4.5.6.7.8.(b) What is synchronous motion? Explain this concept briefly.
