Gravity on the surface of the moon is only

1/6 as strong as gravity on the Earth.
What is the weight of a 15 kg object on the
Earth? The acceleration of gravity is 10 m/s

Huh? You give us useless information about the moon, then ask the weight of a mass on earth?

To calculate the weight of the object on Earth, we can use the formula:

Weight = Mass * Acceleration due to gravity

Given that the mass of the object is 15 kg and the acceleration due to gravity on Earth is 10 m/s², we can substitute these values into the formula:

Weight = 15 kg * 10 m/s²
Weight = 150 kg * m/s²

Hence, the weight of the object on Earth is 150 kg * m/s².
