The acceleration of gravity on Planet Zorg can be found using the formula F=mg, where F is the force exerted on the object, m is the mass of the object, and g is the acceleration due to gravity. Rearranging the formula, we get g=F/m. Plugging in the known values, we get g=180 N/30 kg=6 m/s^2. Therefore, the acceleration of gravity on Planet Zorg is 6 m/s^2. If the same 30 kg barbell were brought to Earth, where the acceleration of gravity is \approx imately 9.8 m/s^2, the motion of the object would change. In this case, a greater force would be required to lift the barbell, as the force of gravity pulling it down is stronger. Additionally, the object would feel heavier on Earth due to the stronger gravitational pull.
