Gravity is a constant force but it`s results are effected my inrertia ,, so jumping up and formarrd will give a curving jump ,, also any object falling in a gravitational feild well accelarete to a terminal velocity.
If ou drop a cannonball onto a surface it WILL bounce ,, it`s all dependant on how much energey the sufrace absorbs
Bropping a large steel ball bearing the size of a cannnon ball onto a steel slab , and the ball will bounce quite high actually ,,, i have done this in the steel works i used to be employed at !! droping it into sand and as sand absorbs most of it`s kenetic energy it bounces verry little (although not easlt vivible the bounce is still there)
As for people .. they can bounce quite spectacularly too ,, i once saw a video of a failed parachute landing onto grass and the guy bounced about 20 feet back ito the air and eventually came to rest ontop of a truck.
The only way to get realistic physics is to model real physics,,, I suggest a book on newtonian physics to help here
