Fill in the blank to complete the correct statement.

In the gravitational pull between two objects, the larger mass experiences a force that is _______ and ________ the force of the smaller mass.

• 1. Equal

  2. In the same direction

• 1. Smaller

  2. opposite

• 1. Larger

  2. Opposite

• 1. Equal

  2. Opposite

• Mass and Gravity are inversely proportional so gravity will decrease.

• Mass and Gravity are inversely proportional so gravity will increase.

• Mass and Gravity are directly proportional so gravity will increase.

• Mass and Gravity are directly proportional so gravity will decrease.

Calculate the Force of Gravity between two shot puts if each shot put has a mass of 7.2 kg and distance of 0.5 meters between them.

In answers ( E = 10^x)

• 2.5 E -8

• 1.38 E -8

• 207

• 6.9 E -9

If an astronomer wanted to find the Force of Gravity between a distant star and an alien planet, what would they need to know?

• All of the Above

• Just the mass of the Planet

• Just the mass of the star

• The distance between the centers of the planet and the star.

If a planet had the same mass as Earth, but triple the radius of Earth, how would the Force of Gravity be different?

• It would be 3 times as strong.

• It would 9 times as strong.

• It would be 1/3 as strong as it is on Earth.

• It would be 1/9 as strong as it is on Earth.

True or False

to find the Force of Gravity between two objects I need to know the distance between the surfaces of the two objects.

• True

• False,

  you need the distance from the centers of the objects

• False,

  the distance doesn't matter

Calculate the Force of Gravity between Saturn and its moon Titan. Saturn has a mass of 5.68 * 10²⁶ and Titan has a mass of 1.35 * 10²³
