Which statement explains why astronauts appear to bounce when they are walking on the moon
A. The force of the air resistance acting on the astronauts is stronger on the moon then on the Earth
B. The force of air resistance acting on the astronauts is weaker on the moon then on earth
C. The force of gravity acting on the astronauts is stronger on the moon then on earth
D. The force of gravity acting on the astronauts as we go on the moon then on the Earth
C. The force of gravity acting on the astronauts is stronger on the moon than on earth.
C. The force of gravity acting on the astronauts is stronger on the moon than on earth.
The correct statement that explains why astronauts appear to bounce when they are walking on the moon is:
C. The force of gravity acting on the astronauts is stronger on the moon than on Earth.
To understand why this is the correct statement, we need to consider the differences between the moon and Earth. The force of gravity is what keeps us grounded on Earth, and it determines our weight. The gravitational force on the moon is about 1/6th that of Earth's gravity. So, if an astronaut weighs 180 pounds on Earth, they would weigh only 30 pounds on the moon.
Since the moon has a weaker gravitational force compared to Earth, the astronauts experience a reduced gravitational pull. This means that when they take steps or try to walk, their bodies are not pulled down as strongly as on Earth. As a result, their movements on the moon appear more buoyant and bouncy, giving the impression that they are "bouncing."
Therefore, option C, stating that the force of gravity acting on the astronauts is stronger on the moon than on Earth, is the statement that explains why astronauts appear to bounce when they are walking on the moon.
