**Does a falling object hit the ground with a force of its mass times "a" of gravity?**

Hi,

When an object is falling through the air and in free fall with no air resistance, the applied force is the net force on the object: the object's mass times the acceleration due to gravity (or -9.8m/s^2). I am wondering if all objects hit the ground with the force of gravitational attraction? If so, then the interraction with the pavement must determine how high the ball bounces. I am learning about momentum and all the collisions are in terms of an object's mass times velocity. I know this is derived from Newton's second law, but I want to look at it terms of f=ma.

What is the initial force that an object hits the ground with? Is this the gravitational force of attraction or m times acceleration due to gravity?
