Multiple choice

The value of g at higher altitudes _____.

  1. decreases

  2. increases

  3. remains the same

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to Newton's law of universal gravitation, gravitational force (and thus g) decreases with the square of the distance from Earth's center. As altitude increases, distance from Earth's center increases, so g decreases. Option B is the opposite of what happens. Option C would mean g is constant regardless of height, which contradicts gravitational law.
