Question

how to calculate surface gravity on planet mars

Answer 1

You have learned that the surface gravity (g) of a body depends on the mass (M) and the radius (r) of the given body. The formula which relates these quantities is:
g = G * M / r2
where G is called the Gravitational constant. Remember that the notation r2 means r to the 2nd power, or r squared.

You will calculate the surface gravity for a number of bodies using the MKS system where the units for distance are meters, the units for mass are kilograms, and the units for time are seconds. In this system, the gravitational constant has the value:

G = 6.67 * 10-11 Newton-meter2/kilogram2.
