On the Moon, astronauts experienced gravity which is less than they had known on Earth. Moon's mass is 0.012 (0.12 percent) of Earth's mass, and its radius is 0.27 times Earth (27%). Therefore gravity on the Moon is only 0.16 or 16% of Earth's gravity. A falling object on the Moon accelerates at about 1.6 m/s2. If the Earth only had Moon's mass and still had its present size, how fast would a falling body on Earth accelerate?
1.6 m/s2
0.12 m/s2
9.8 m/s2
82 m/s2
Definition Definition Fundamental law of forces which states: “For every action, there is an equal and opposite reaction." In other words, whenever one body exerts a force on a second body, the second body exerts an oppositely directed force of equal magnitude on the first body. It is also called the “action-reaction law” and was defined by Sir Isaac Newton.
