Objects on the moon's surface have an acceleration due to gravity one-sixth that on the earth's. What would the 40 kg boy weigh on the moon? (Round answer to nearest tenth.)
acceleration is the same as the gravitational force. On earth that is 9.81 m/s^2. F=ma so if the acceleration is 1/6, then so if the force (weight). 40/6 N is your answer.
