Second law of motion apparatus
notes: label: Description
content: Alfred Payson Gage (1836-1903) opened America’s first high school physics laboratory, at the Boston English High School, in 1880. He also wrote textbooks that were widely used, and designed simple instruments suitable for students. This Second Law of Motion apparatus was among those instruments. It has a spring hammer that propels one ball and releases another at the same instant. Both balls reach the floor at the same time, although one follows a parabolic arc while the other falls straight down.
