| Abstract | In introductory physics courses, within the context of studying Newton's laws, it is common to consider the problem of a body's "weight" when it is in free fall. The solution shows that the "weight" is zero and this leads to a discussion of the concept of weight. There are permanent free-fall situations such as astronauts in a spacecraft orbiting the Earth, for example, the International Space Station. However, it is important for an astronaut's health to control any variations in his/her body mass while on the orbiting spacecraft. This paper examines the following scenario: How can astronauts be weighed while in free fall? (As Provided). |
