Solution

Understanding Gravitational Strength

  1. Gravitational Strength Concept: Gravitational strength, or gravitational acceleration, is the force of gravity acting on an object. It depends on the mass of the Earth and the distance from its center.

  2. Gravitational Force Equation: The gravitational force F F between two masses can be expressed by Newton's law of universal gravitation: F=Gm1m2r2 F = \frac{G \cdot m_1 \cdot m_2}{r^2} where:

    • G G is the universal gravitational constant,
    • m1 m_1 and m2 m_2 are the masses,
    • r r is the distance between the centers of the two masses.
  3. Effect of Distance on Gravity: As the distance r r (from the center of the Earth) increases, the gravitational force F F decreases because it is inversely proportional to the square of the distance (r2 r^2 ). Hence, the further an object is from the Earth, the weaker the gravitational pull it experiences.

Conclusion

Based on this understanding, as the distance from the Earth's surface increases, the gravitational strength decreases.

Final Answer

Decreases.
