When an astronaut is on a spacewalk and is moving away from the space shuttle, how does the force of gravity between the two objects change? (1 point)
A. it goes up for the astronaut and goes down for the space shuttle
B. it goes up
C. it goes down for the astronaut and goes up for the space shuttle
D. it goes down
C. it goes down for the astronaut and goes up for the space shuttle
C. it goes down for the astronaut and goes up for the space shuttle.
To understand how the force of gravity changes between an astronaut and a space shuttle during a spacewalk, we need to consider Newton's law of universal gravitation. According to this law, the force of gravity between two objects depends on their masses and the distance between them.
As the astronaut moves away from the space shuttle during the spacewalk, the distance between them increases. According to the law of universal gravitation, the force of gravity decreases as the distance between two objects increases. Therefore, the correct answer is:
C. The force of gravity goes down for the astronaut and goes up for the space shuttle.
