Hundreds of years ago Galileo found that one could “slow down” the acceleration by not letting things fall straight down. Rather, he made them “fall” at an angle; in other words, he let them fall down an inclined plane. In this way, they didn’t cover as much distance in a given time interval and the change in speed was slower.
