Short Answer

An astronaut takes his bathroom scale to the moon and then stands on it. Is the reading of the scale his weight? Explain.

The weight of the astronaut on the moon is indicated by the scale readout. Due to the lunar gravity effect on the astronaut, the indicated value of the astronaut is of the weight of the astronaut on Earth.

Step by Step Solution

Step 1 : Introduction

An astronaut travels to the moon with his bathroom scale and stands on it.

Step 2 : Explanation

The weight is a term used to describe the objects that have gravitational force on one other. The gravity value of the moon is that of the earth, implying that the moon's gravity value is of the earth's gravity value.

Step 3 : Explanation

The weight of the astronaut on the moon is indicated by the scale readout. Due to the lunar gravity effect on the astronaut, the indicated value of the astronaut is of the weight of the astronaut on Earth. No, due to gravity's effect on the astronaut, the readout on the scale does show the weight of the astronaut as he was on the earth's surface.
