The Golf Ball

4 tests · 40 facts · updated 13 October 2026 · markdown

The modern ball: how it is built, how it is tested and limited, choosing one, and why it flies.

Each test below is ten questions on Insporta. The list under a test is what the questions check: one fact per question, with the source it was written from. Read it before the test, or come back from a wrong answer.

Test 4Why it fliesTake a test

  1. It keeps the ball in the air longer.
