Question

part c
now, set the mass of both balls to be equal. increase the distance between them by pulling one of the balls away from the other. to pull a ball away, click on the ball and drag it. what happens to the force arrows between the two balls? what does this mean in terms of gravity?

Analyze the effect of distance on force arrows

Using the Gravitational Force Factors knowledge point
\[
F \propto \frac{1}{r^2}
\]
As the distance \(r\) between the two balls increases, the magnitude of the gravitational force \(F\) decreases. Consequently, the force arrows representing this gravitational attraction become shorter.

Interpret the physical meaning in terms of gravity

Using the Universal Law of Gravitation knowledge point
\[
F = G \frac{m_1 m_2}{r^2}
\]
This demonstrates that the gravitational attraction between two objects is inversely proportional to the square of the distance separating them, meaning gravity weakens as objects move further apart.

<answer>
As the distance between the two balls increases, the force arrows between them become shorter. In terms of gravity, this means that the gravitational force of attraction between two objects decreases as the distance between them increases.
