Science explains why basketball sneakers squeak
Чтение
Adel Djellouli watched a basketball game and heard a sound. The squeaking noise from shoes was always there.
Djellouli is a scientist and wanted to know more. He slid a shoe on glass and used a camera.
They learned that shoe soles change shape very quickly. This fast movement creates the loud squeaking sound.
Understanding friction helps solve big science problems. It can explain earthquakes and save energy too.
This research can help design shoes without squeaks. Scientists might control shoe sounds in the future.
