Question 18 • Physics

If all else stays the same, which change could be made to cause an increase in the gravitational force on a space shuttle?

Answer
A
decreasing the universal gravitational constant acting on the space shuttle
B
increasing the universal gravitational constant acting on the space shuttle
C
increasing the distance of the space shuttle from Earth
D
decreasing the distance of the space shuttle from Earth

Explanation

Newton’s law of gravitation is F = Gm₁m₂/r², so with the masses and gravitational constant unchanged, the force increases when the distance r decreases. Therefore, decreasing the shuttle’s distance from Earth increases the gravitational force. Increasing the distance would make the force weaker.
