Question

which of the following are true about the impact of newtons law of universal gravitation?
select all that apply
a it suggested that gravity is not universal and only affects certain objects.
b it explains the motion of objects not only on earth but in outer space as well.
c it led to a better understanding of the universe and the forces at play.
d it was the first scientific law that applied to the entire universe.
e it disproved the existence of gravity.

Explanation:

• Option a: Newton's Law of Universal Gravitation states that gravity is universal and acts between all objects with mass. So, this option is false.
• Option b: The law explains the motion of objects on Earth (e.g., an apple falling) and in outer - space (e.g., the orbit of the Moon around the Earth). This option is true.
• Option c: By formulating the law of universal gravitation, Newton provided a framework to understand the forces (gravity) that govern the motion of celestial and terrestrial objects, leading to a better understanding of the universe. This option is true.
• Option d: Newton's Law of Universal Gravitation was one of the first scientific laws that proposed a force (gravity) acting throughout the entire universe, applicable to all objects with mass. This option is true.
• Option e: The law of universal gravitation is about the nature and behavior of gravity, not about disproving its existence. This option is false.

Answer:

B. It explains the motion of objects not only on Earth but in outer space as well.
C. It led to a better understanding of the universe and the forces at play.
D. It was the first scientific law that applied to the entire universe.
