In an argument about baseball, Dr. Stephen Franklin states, "...Martian gravity is 40 percent less than Earth normal. The ball travels faster and further..." Martian gravity is even weaker than that: a bit under 2/5 of Earth's, not 3/5 as Franklin says. Either way, it is true that in lower gravity a ball hit at a given speed and angle takes longer to reach the peak of its arc, and thus covers more horizontal distance, in proportion to the difference in gravity.
