ARE YOU READY??? (S8P5.a)

Emma and Rohan are playing with two balls that are two meters apart. Which of these changes will increase the gravitational force between the two balls?

• Emma decreases the mass of her ball

• Both Emma and Rohan decrease the mass of their balls

• They move the balls to one meter apart

• They move the balls to three meters apart

Why does a feather fall slower on the Moon than on Earth?

• Because the Moon has a smaller surface area than Earth.

• Because the mass of a feather on Earth is greater than on the Moon.

• Because the gravitational field of the Moon is less than that of Earth.

• Because the atmosphere of the Moon is much thinner than that of Earth.

Lily, Nora, and Abigail are curious to know whether Callie or Dennis is feeling the most pull from Earth's gravity during their physics class experiment. How can they determine this?

• by determining which person has the most volume, because they will have more gravitational pull

• by determining which person has the most mass, because they will have more gravitational pull

• by determining which person is stronger, because they will have less gravitational pull

• by determining which person is faster, because they will have less gravitational pull

Charlotte, Oliver, and Noah are studying physics. They are discussing the factors affecting the gravitational force between two objects. Which statement correctly describes their conclusion?

• Gravitational force between two objects is determined by their masses and the distance between their outermost edges.

• Gravitational force between two objects is determined by their masses and the distance between their centers.

• Gravitational force between two objects is determined by their volumes and their acceleration relative to the Sun.

• Gravitational force between two objects is determined by their diameters and their distance from the Sun.

Nora, Priya, and Grace are discussing about the nature of gravitational force. Nora says that objects exert a gravitational force on every other object. Which statement best describes Nora's view on gravitational force?

• Objects exert a gravitational force on every other object.

• Objects exert a gravitational force only on objects close to them.

• Only objects with a large mass exert gravitational force on every other object.

• Only objects with a large mass exert gravitational force on objects close to them.

Mia and Emma are discussing about the gravitational force between two objects. Mia claims that it depends on the mass of the objects and the distance between them. Emma, however, is not sure. Aria, who is listening to their conversation, decides to intervene. Which argument should Aria use to best support Mia's claim?

• If the Earth were much bigger, the gravitational force between Earth and the Moon would be higher.

• If the Earth were much bigger, the gravitational force between Earth and the Moon would be lower.

• If the Earth were much bigger, the gravitational force between Earth and the Moon would not change.

• If the Earth were much bigger, the gravitational force between Earth and the Moon would disappear.

William and Rohan are discussing about gravitational forces. Hannah joins them and makes a few statements. Which of the following statements made by Hannah is true about gravitational forces?

• Gravitational forces are larger between a feather and a book that have small masses.

• Gravitational forces are smaller between the Earth and the Moon that have large masses.

• Gravitational forces decrease as the distance between a football and a player decreases.

• Gravitational forces increase as the distance between a satellite and the Earth decreases.
