A Person Orbiting Earth in the Space Shuttle Feels Weightless

question 61

Multiple Choice

A person orbiting Earth in the space shuttle feels weightless because:

• A) two forces are acting on her in opposite directions, so they cancel and produce the same effect as if no force at all were acting.
• B) her mass is zero in space, and weight requires mass.
• C) no forces act on her.
• D) only one force (gravity) acts on her, but gravity also accelerates the Shuttle, so the Shuttle does not push up on her to create the feeling of weight.
