Question

The force of gravity on an object varies directly with its mass. The constant of variation due to gravity is 32.2 feet per second squared. Write an equation represents f

Answer 1

The force F = m g

Explanation:

The gravitational force of attraction on the object can be found by the relation

F = G M m/R²

here G is the gravitational constant

M is the mass of earth

and R is the radius of earth

All these terms remains constant , therefore the force varies with the mass of body i.e. m

This constant term i.e GM/R² is represent by g , acceleration due to gravity

Thus Force F = m g
