Key differences
ball — /ɔː/— the most open back vowel. Jaw drops, mouth wide. Like saying “aw” — your mouth is open.
pole — /oʊ/— a diphthong that glides. Start with rounded lips, then they push forward. Mouth is more closed than “ball”.
pool — /uː/— lips very rounded and pushed forward, tongue high at the back. Hold it long. Tighter and higher than “pole”.
