what would the astronauts mass be on the lunar surface?
The mass would be the same
To calculate the mass of an astronaut on the lunar surface, we need to understand the difference between mass and weight.
Mass refers to the amount of matter an object contains and is measured in kilograms (kg). It is a constant value and remains the same regardless of the location.
Weight, on the other hand, is the force of gravity acting on an object's mass and is measured in newtons (N). Weight can vary depending on the strength of gravity at a particular location.
The gravitational force on the moon is approximately 1/6th of the gravitational force on Earth. Therefore, an astronaut's weight on the moon would be approximately 1/6th of their weight on Earth.
To calculate the astronaut's weight on the moon, you would multiply their mass by the acceleration due to gravity on the moon.
The acceleration due to gravity on the moon is approximately 1.6 meters per second squared (m/s²).
So, if you know the astronaut's mass on Earth, you can find their mass on the lunar surface by multiplying it by 1/6 to account for the reduced gravity.
