Summary
Mark straps a rocket to a golf club to swing it far faster than any human could, then films the ball launch at 100,000 frames per second. The slow-motion reveals how energy transfers in the split-second of impact.

Discussion questions
Talk about it
A faster club carries more energy of motion. When it strikes the ball, that energy transfers in a tiny instant — the super-slow camera lets us see it.
- Why does swinging the club faster send the ball farther?
- What happens to the ball's shape at the moment of impact, and why?
- How does filming at 100,000 frames per second help scientists study a fast event?
Quick work-a-long
Vocabulary: energy of motion, speed, impact, energy transfer.
Try it: Flick a marble slowly, then hard, into a row of coins. Compare how far the coins move. Explain with the words speed and energy.
