Explaining How Momentum Can Cause An astronaut on a space walk floats a little too far away
from the space station. Without air to push against, he
cannot paddle back. However, the astronaut is holding a
hammer. Explain how the astronaut could use the
hammer to move and why this will get him back to the
space station.

Explain what happens at the saturation point when adding salt to water at room temperature.
