Question

What is the acceleration due to gravity on the surface of the Moon? On the surface of Mars? The mass of Mars is 6.418 × 10^23 kg, and its radius is 3.38 × 10^6 m.

a) 1.62 m/s^2; 3.76 m/s^2
b) 3.76 m/s^2; 1.62 m/s^2
c) 9.81 m/s^2; 3.76 m/s^2
d) 1.62 m/s^2; 9.81 m/s^2

Answer 1

The acceleration due to gravity on the surface of the Moon is 1.62 m/s², and on the surface of Mars it is 3.76 m/s².

Step-by-step explanation:

The acceleration due to gravity on the surface of the Moon is 1.62 m/s², while the acceleration due to gravity on the surface of Mars is 3.76 m/s². This means that objects on the Moon will experience only about 1/6th of the gravitational pull they experience on Earth, while on Mars they will experience about 3/8th of the gravitational pull.

The formula to calculate the acceleration due to gravity on the surface of a planet is:

g = G * M / r^2

Where g is the acceleration due to gravity, G is the gravitational constant, M is the mass of the planet, and r is the radius of the planet.
