80 POINTS, BRAINLIEST, AND QUESTION IS MULTIPLE CHOICE!!! (please answer quickly) question:

If all matter has a gravitational force, why don’t two tennis balls on the ground move towards each other on their own?

A. The force of gravity from the tennis balls is too small.
B. The tennis balls are outside of each other’s gravity field.
C. The tennis balls are too small to produce any gravity.
D. There is too much friction between the balls and the ground
(the picture is just of the question)

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Explanation:

I could be wrong but I would say B :)

Have a good day!

i believe the answer is d

explanation:

here's why;

c. is incorrect because everything has a gravitational force.

a. is also incorrect because gravity is what holds the tennis ball down and keeps it on the ground.

i don't really know how to explain why b. is wrong, but d. is the correct answer because the force of friction opposes the motion of an object, causing moving objects to lose energy and slow down.

good luck :)

i hope this helps

**please let me know if this was incorrect**

have a great day !!

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
