Newton’s law of gravitation. It may come very easy for you, or it may take an
awful lot of hard work. You may have had previous experience with this and
only need enrichment of the lesson.

A. 6.673 x10^11
B. 6.672 x10^-11
C. 6.673 x10^-11
D. None of the above
__________3. The following statements are TRUE about gravitational force EXCEPT _______________________.
A. Gravitational force is the force of attraction between objects
B. Gravitational force is one of the quantities in the gravitation equation.
C. Gravitational force depends only in the masses of objects.
D. None of the above.
__________4. Which is TRUE about the mass between objects?
A. The mass of the object Increases if the gravitational force present on the object increases.
B. The mass of the object decreases if the gravitational force present on the object increases.
C. The mass of the object Increases if the gravitational force present on the object decreases.
D. None of the above.
__________5. Which of the following statement best explains the concept of acceleration due to gravity?
A. Acceleration due to gravity is always constant.
B. Acceleration due to gravity is equivalent to 9.8 m/s.

Directions: Analyze and solve the problem below. Show your solution on the space provided.
The distance between Earth and moon is 3.84 x 10^8 m. If the masses of the Earth and the moon are 5.9742 x10^24 kg and
7.36 x10^22 kg, respectively, what is the force of attraction between Earth and the moon?
Choose one and answer.
A .Directions: Using your knowledge of Newton’s Universal Law of Gravitation, reflect on the following question and try to
answer. Write your answer on your reflection notebook.
A. As a star ages, it is believed to undergo variety of changes. One of the last phase of the star’s life is gravitationally collapse into a black
hole. What will happen to the orbit of the planets of the solar system if our star (the sun shrinks into a black hole)?
B. Having completed her Physics course, Dawn has devised a new business pla based on her teacher’s Physics for Better Living Theme.
Dawn learn that objects weigh different amounts at different distances from Earth’s center. Her plan involves buying gold by the weight at
one altitude and then selling it at another altitude at the same price per weight. Should Dawn buy at high altitude and sell at low altitude or
vice versa? Why?
C. When comparing the mass and size ata for the planets Earth and Jupiter, it is observed the Jupiter is about 300 times more massive than
Earth. One might quickly conclude that an object on he surface of Jupiter would weigh 300 times more than one on the surface of the Earth.
For instance, one might expect a person who weighs 500N on Earth would weigh 150000N on surface of the Jupiter. Yet this is not the
case. In fact, a 500 N person on Earth weighs about 1500N on he surface of the Jupiter. Explain how can this be.
