Athletes can compare their motion with an expert and fix small mistakes.

The Big Idea

Slow motion shows things too fast to see! How does it help athletes? Let's slow down.

High Speed

Step one: High Speed. A high-speed camera records many more frames per second than normal video. When played back slowly, it shows details the eye cannot see, such as how the wrist of a pitcher turns.

Measuring

Improving

Step three: Improving. Athletes can compare their motion with an expert. Then they fix small mistakes.

Outro

A high-speed camera records many more frames per second, so slow playback shows details the eye misses. Coaches draw lines to measure angles, and athletes compare their motion with experts to fix small mistakes. Slow motion turns a blink into a story you can watch again and again, so you can learn something new each time. Science is amazing! The world is full of surprises.
