how would the force Of gravity by the Sun on the Earth change?
A: It would become four times stronger.
B: would become four times weaker.
C: It would be unchanged.
D: It would become two times stronger.
E: It would become two times weaker.
Ans: A: It would become four times stronger.
What did Newton' Law Of universal Gravitation tell us about how
gravity works?
A: The force will be weaker on an Object that is closer to Sun
than one farther from the Sun.
B: Gravity only works on the surface of planets, and there is no
gravity in space.

If you were to sit on the ground, there would be a force to
gravity pulling you toward the Earth. Which of the following is true
to Newton's 3rd law?
A: you are pulling the Earth toward yourself with the same force
B: you are not exerting any force on the Earth
C: you are pushing the Earth away With Same

Ans: A: you are pulling the Earth toward yourself with the same
force
What would to the Earth if the Sun's gravity somehow turned
Off instantaneously?
A: It Would continue to orbit Without any changes.
