C165 NASA has used this same idea to "weigh" astronauts during space missions. They developed a device in which the astronaut glides back and forth by being pushed and pulled by springs. The springs apply the same force during each swing. The velocity of the astronaut is constantly changing as the force from the spring accelerates him first one way, then the other. If the astronaut has lost weight while in space, would the spring accelerate him back and forth more easily or less easily?
