Earth has a mass of 5.98 x 10^24 kg and a radius of 6.38 x 10^6 km. explain why the acceleration due to gravity on mars is different than on earth *

It is because Earth's mass and radius are different from Mars's mass and radius.

Explanation:

From Newton's gravitational law;

;

Where;

g is acceleration due to gravity

G is universal gravitation constant

R is the radius of the planet

M is the mass of the planet

From the equation above, acceleration due to gravity is directly proportional to the mass of the planet and inversely proportional to the square of the radius of the planet.

Earth's mass and radius are different from Mars's mass and radius.
