13. Which one of the following accurately describes the force of gravity? A. The gravity acceleration is in the same direction as the force of gravity, and thus away from the center of the earth. B. The force of gravity is slightly lower at the bottom of a mountain than it is at the top. C. The gravity acceleration has no effect on a body moving in directly the opposite direction of the force of gravity. D. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
Question
- Which one of the following accurately describes the force of gravity? A. The gravity acceleration is in the same direction as the force of gravity, and thus away from the center of the earth. B. The force of gravity is slightly lower at the bottom of a mountain than it is at the top. C. The gravity acceleration has no effect on a body moving in directly the opposite direction of the force of gravity. D. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
Solution
The correct answer is D. The gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth.
Here's why:
Gravity is a force that attracts two objects towards each other. On Earth, gravity gives weight to physical objects and causes the ocean tides. The gravitational force is always directed towards the center of the Earth. This is why we always fall downwards when we trip or drop something.
Option A is incorrect because the force of gravity is directed towards the center of the Earth, not away from it.
Option B is incorrect because the force of gravity is actually slightly higher at the bottom of a mountain than at the top. This is because gravity decreases with altitude.
Option C is incorrect because gravity affects all objects, regardless of their direction of movement. Even if an object is moving directly opposite to the direction of the force of gravity, it will still be affected by gravity.
