When interplanetary space travel becomes viable, doctors may suggest to people with arthritis that they vacation on a planet with lower gravitational attraction and do more walking.
The gravitational acceleration on Earth is 9.8 m/s 2
, while the gravitational acceleration on Mars is 3.7 m/s 2
. How much less force would the vacationer be applying to their joints when walking on Mars?

Explanation: The force exerted on an object is calculated by multiplying its mass by the acceleration due to gravity. Since the acceleration due to gravity on Mars is 3.7 m/s^2, the force exerted on a person's joints when walking on Mars would be 9.8/3.7 = 2.6 times less compared to walking on Earth.
