One kg weighs 9.8 N on Earth. Would it weigh more or less on the Moon?

Less. One-sixth as much.

10.8kg

On the Moon, an object would weigh less compared to Earth. This is because the force of gravity on the Moon is much weaker than that on Earth. The Moon has about 1/6th of Earth's gravity.

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

Weight on the Moon = Weight on Earth × (Gravity on the Moon / Gravity on Earth)

Given that the weight of 1 kg on Earth is 9.8 N, we can calculate the weight on the Moon as follows:

Weight on the Moon = 9.8 N × (1/6)

Weight on the Moon = 1.63 N

Therefore, one kilogram would weigh approximately 1.63 Newtons on the Moon, which is significantly lighter than its weight on Earth.
