Question

Which of the following has the greatest impact on producing injury?

1) Gravity
2) Distance
3) Mass
4) Speed

Answer 1

A safe fall on the Moon could be six times higher than on Earth since the Moon's gravitational acceleration is about 1/6th of Earth's, leading to a lower impact speed upon landing.

Step-by-step explanation:

The severity of a fall depends on the speed at which you strike the ground. In determining the impact of a fall on Earth versus the Moon, one must consider the difference in gravitational acceleration. Since the Moon's gravitational acceleration is approximately 1/6th that of Earth's, a safe fall could technically be six times higher on the Moon compared to Earth, assuming all other factors are equal. This is because gravitational force affects the speed at which you fall—lesser gravity on the Moon means you would accelerate slower and thus hit the ground with less speed.
