part a\nones weightlessness in space has most to do with ______.\nview available hint(s)\nhint 1.\nhow is weight defined in general?\nones mass\nno gravity\nrotational effects\nno support force
Answer
Brief Explanations:
Weight is the force exerted on an object due to gravity and the support force. In space, when an object is in free - fall, there is no normal support force acting on it, which gives the sensation of weightlessness. Mass is a measure of the amount of matter and is not the cause of weightlessness. There is gravity in space, just at a reduced level in some cases. Rotational effects are not the main cause of weightlessness.
Answer:
D. no support force
