What is the center of gravity?

How to think about it

1. In physics, the center of gravity is the balance point of an object. The hint says to spell, so set physics aside.
2. Write the word: g-r-a-v-i-t-y. It has seven letters.
3. The middle letter of seven is the fourth.
4. The fourth letter of “gravity” is V.

Why “the letter V” is the answer

The word “gravity” has seven letters, and the one in the exact center is V, so the letter V is the center of gravity. The riddle relies on the physics phrase being so familiar that you do not think to look at the word. Seven letters make the middle unambiguous.

Common wrong answers

• The Earth’s core. That is where gravity seems to pull, but the riddle wants the letter in the middle of the word.
• The letter A. A is the third letter, not the fourth, so it is just off center.
