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?
