Gravity on the surface of the moon is only 1
as strong as gravity on the Earth. 6 What is the weight of a 30 kg object on the Earth? The acceleration of gravity is 10 m/s2 .

To calculate the weight of an object on Earth, you need to use the formula:
Weight = mass × acceleration due to gravity.
Given that the mass of the object is 30 kg and the acceleration due to gravity on Earth is 10 m/s^2, we can substitute these values into the formula.
Weight = 30 kg × 10 m/s^2
Weight = 300 kg·m/s^2.
Now, the unit for force is Newton (N), where 1 N is equal to 1 kg·m/s^2. So, we can convert the unit to N by dividing by 1 kg·m/s^2:
Weight in N = 300 kg·m/s^2 ÷ 1 kg·m/s^2.
Therefore, the weight of a 30 kg object on Earth is 300 N.
