When an astronaut is on a spacewalk and is moving away from the space shuttle, the force of gravity between the two objects decreases. So, it goes down for both the astronaut and the space shuttle.
The correct response is "it goes down for the astronaut and goes up for the space shuttle."
When an astronaut is on a spacewalk and moves away from the space shuttle, the force of gravity between the two objects decreases. This is because the force of gravity is directly proportional to the mass of the objects involved and inversely proportional to the square of the distance between them. As the astronaut moves farther away from the space shuttle, the distance between them increases, causing the force of gravity between them to decrease.
To understand why this happens, you can use Newton's law of universal gravitation, which states that the force of gravity between two objects is given by the formula F = (G * m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them. In this case, the mass of the astronaut remains the same, but the distance between the astronaut and the space shuttle increases, causing the force of gravity to decrease.
