An object has a mass of 120 kg on the moon. The force of gravity acting on the object on the moon is 196N. Force = mass.acc, Force = 120. 9.8 /6 = 196N Added 192 days ago 5/23/2020 12:17:36 AM. It depends on context. In the field of trade etc, it is 20 kg. In the field (s) of STEM, it is close to 200 N. If you care enough to complain about my (quite good) approximation, you already know that Earthly gravity in SI starts with a 9.8, not 10.

To figure out d, we can use trigonometry. We can write the following:

If, you wanted, you can also figure out F_{AB} by substituting the value of theta we found back into eq.1.F_{AB},=,dfrac{100}{text{cos},(63^0)}
