Question
You've learned to juggle 4 balls at once here on Earth. During a visit to the moon, where the acceleration due to gravity is about 1/6th its Earth value, you decide to try juggling those same 4 balls. You find that, on the moon, each ball has ________________.1 pointless weight and falls more slowly than on Earth. It undergoes the same acceleration as on Earth when exposed to the same force as on Earth.less weight and falls more slowly than on Earth. It accelerates more rapidly than on Earth when exposed to the same force as on Earth.the same weight, but falls more slowly than on Earth. It accelerates more slowly than on Earth when exposed to the same force as on Earth.the same weight and falls at the same rate as on Earth. It accelerates more slowly than on Earth when exposed to the same force as on Earth.
Solution
The correct answer is: "less weight and falls more slowly than on Earth. It accelerates more rapidly than on Earth when exposed to the same force as on Earth."
Here's why:
-
The weight of an object is the force of gravity acting on it. Since the acceleration due to gravity on the moon is about 1/6th its Earth value, the weight of each ball on the moon is less than its weight on Earth.
-
The rate at which an object falls (its acceleration due to gravity) is also less on the moon than on Earth, so each ball falls more slowly on the moon than on Earth.
-
The acceleration of an object is determined by the net force acting on it and its mass, according to Newton's second law of motion (F=ma). If the same force is applied to a ball on the moon as on Earth, the ball will accelerate more rapidly on the moon because its weight (and therefore the force of gravity acting on it) is less.

6. Astronauts visiting the moon collect and measure rock samples. Rock A is a 2 kg rock that weighs 1 N on the moon. Rock B is a 4 kg rock that weighs 2 N on the moon. How and why are the weights of these rocks likely to change once the rocks are brought back to Earth? aBoth rock samples are likely to weigh more on Earth because their masses will increase.bBoth rocks are likely to weigh less on Earth because their masses will increase.cBoth rocks are likely to weigh less on Earth because they are from the moon, which exerts a weaker gravitational force than Earth.dBoth rocks are likely to weigh more on Earth because Earth exerts a stronger gravitational force on their respective masses than the moon.
