Sir , 
I am using a basic overlap amount to find the force on the bouncing ball. And compute the position of the Ball. I have a  following concept question.

When the ball is in the air the only force acting is gravity. So from gravitational force we can compute the acceleration and the position. Through the explicit euler integration I found the position of the ball until it interacts with the wall.  

Once it interacts with the wall I found the overlap amount and from the material properties of both the spheres, I computed the force acted upon the bouncing ball by the sphere. So I will get a positive force upward and for the next time step that positive force addition to the gravity, will be considered to compute the position.  Exactly after that one time step if we again compute, we get only gravitational force and the ball will com down. 

But in general, the ball has to go up until its velocity has to become zero.  And ther it has to repeat the same. So how can I model this using force, to compute the position of wall? 


Thank you
