Question

more, less, or the same as on the earth
when an astronaut lands on the moon:
the astronauts mass is:
the astronauts weight is:
the astronauts inertia is:

Explanation:

• Mass: Mass is a measure of the amount of matter in an object. It does not change with location. So, the astronaut's mass is the same as on Earth.
• Weight: Weight is the force of gravity acting on an object, calculated as \(W = mg\) (where \(m\) is mass and \(g\) is the acceleration due to gravity). The moon's gravity (\(g_{moon}\approx1.62\ m/s^{2}\)) is less than Earth's (\(g_{earth}\approx9.8\ m/s^{2}\)). Since \(m\) is constant and \(g\) is smaller on the moon, the astronaut's weight is less than on Earth.
• Inertia: Inertia is a property of matter related to its mass. As mass is unchanged, the astronaut's inertia is the same as on Earth.

Answer:

• The astronaut's mass is: the same as on the Earth.
• The astronaut's weight is: less than on the Earth.
• The astronaut's inertia is: the same as on the Earth.
