The correct statement is: "The force of gravity acting on the astronauts is weaker on the moon than on Earth."
To understand why astronauts appear to bounce when walking on the moon, we need to consider the difference in gravity between the moon and Earth. Gravity is a force that pulls objects towards each other. On Earth, the force of gravity is much stronger compared to the moon.
On the moon, the gravity is approximately 1/6th of the gravity on Earth. This means that objects and astronauts have less weight and feel lighter on the moon. When astronauts take a step on the moon's surface, their weight is much lighter than on Earth, causing them to exert less downward force on the ground.
As a result, when their foot pushes against the surface, the force of gravity is not strong enough to hold them down firmly. Instead, they can easily push off and bounce back into the air. This bouncing effect was particularly noticeable during the Apollo moon missions when astronauts were filmed hopping around the lunar surface.
