**Weight** is determined by multiplying the mass of an object in kilograms times the acceleration due to gravity.

W = m x g

W = weight in Newtons

m = mass in kg

g = acceleration due to gravity in m/`~s^2`

** Step 1: Determine the mass of...**

**Weight** is determined by multiplying the mass of an object in kilograms times the acceleration due to gravity.

W = m x g

W = weight in Newtons

m = mass in kg

g = acceleration due to gravity in m/`~s^2`

**Step 1: Determine the mass of the object.**

The acceleration due to gravity on the moon is equal to: 1.622 m/`~s^2` .

The weight on the moon is equal to: 100 N

Plugging these values into the formula for weight enables us to calculate the mass of the object in kilograms.

100 N = mass x 1.622

**mass** = 100/1.622 = **61.7 kg**

**Step 2: Determine the weight of the object on Earth.**

The acceleration due to gravity on Earth is equal to: 9.8 m/`~s^2` .

The mass of the object on Earth will be the same as the mass of the object on the moon: 61.7 kg

Plugging these values into the formula for weight enables us to calculate the weight of the object on Earth.

weight = 61.7 x 9.8 = **605 N**
