The weight of an object on earth is 350 Newton’s. On mars, the same object would weigh 134 Newton’s. What is the acceleration due to gravity on the surface of mars, given that is it is 9.8 meter/second^2 on earth?
From this simple formula for weight, you can see that an object's weight is directly proportional to the acceleration of gravity in the place where the object is located.
If the object weighs 350 N on Earth and 134 N on Mars, then we can write
