What is the gravitational acceleration value for Mars?
Answer The gravitational acceleration at the surface of any planet can be determined from a = G*m/r^2 where G is the universal gravitational constant, m is the mass of the planet and r is the radius of the planet. If you want to find the acceleration on the surface of Mars just use the corresponding information for Mars!
