answer the following multiple choice questions about the reading( reading is linked on google classroom as
ewton and gravity\.

1. according to the passage, what is gravity?

a. a measurement of an objects weight
b. the absence of force
c. a force that pulls everything together
d. a type of floating device

1. according to newtons law of universal gravitation, what happens if an object has more mass?

a. it floats away from other objects
b. it shrinks in size
c. it pulls harder on other objects
d. it becomes lighter

1. what phenomenon is caused by the moons gravitational pull on the earth?

a. changes in weather patterns
b. volcanic eruptions
c. tides in the ocean
d. earthquakes

Explanation:

• Question 10: Gravity is a fundamental force. Option C aligns with the concept that gravity is a force of attraction (pulling everything together). Option A is incorrect as weight is \(W = mg\) (mass \(m\) times gravitational acceleration \(g\)), not gravity itself. Option B is wrong because gravity is a force, not the absence of it. Option D is a mis - understanding as gravity is not a device.
• Question 11: According to Newton's Law of Universal Gravitation \(F=\frac{Gm_1m_2}{r^{2}}\) (where \(G\) is the gravitational constant, \(m_1\) and \(m_2\) are masses of two objects, and \(r\) is the distance between their centers). As \(m\) (mass of an object) increases, the gravitational force \(F\) it exerts on other objects increases. So, an object with more mass pulls harder on other objects (Option C). Options A, B, and D are not in line with the law.
• Question 12: The Moon's gravitational pull on the Earth causes tides in the ocean. Weather patterns (Option A) are mainly influenced by factors like temperature, pressure, and wind. Volcanic eruptions (Option B) and earthquakes (Option D) are related to the Earth's internal geological processes, not the Moon's gravitational pull.

Answer:

1. C. A force that pulls everything together
2. C. It pulls harder on other objects
3. C. Tides in the ocean
