To calculate g, we use the formula F = mg. F is given as 180N, and m is given as 30 kg, therefore:

180N = (30kg) (g)

g = 6 m. s-1.

The motion of this object would be decreased on Earth as more force would be required to lift it. If we assume g is 9.8 m. s-1 on Earth, we can calculate the force required.

F = mg

= (30kg) (9.8 m. s-1)

= 294 N
