Question

1. choose the best answer.

• decreases
• increases
• moves in an increasingly tighter circle
• reverses direction

1. choose the best answer.

as mass increases, gravitational force ______.

• increases
• decreases
• generates electric energy
• becomes unstable

Explanation:

Question 3

The law of universal gravitation is \( F = G\frac{m_1m_2}{r^2} \), where \( F \) is gravitational force, \( r \) is the distance between masses. As \( r \) (distance) increases, \( F \) (gravitational force) decreases because \( F \) is inversely proportional to the square of \( r \).

From \( F = G\frac{m_1m_2}{r^2} \), gravitational force \( F \) is directly proportional to the product of the masses (\( m_1, m_2 \)). So as mass increases, \( F \) (gravitational force) increases.

Answer:

A. decreases
