统一中的轨道路径（非牛顿方法）

Question

After developing a Newtonian gravity based physics engine in my game using Unity2D , which is about a ball being kicked by players around Earth and possibly attracted by Moon and shot in various destinations as a goal, I have seen that ball's motions can be quite boring.

Therefore, did some research and seen how Mario fixed the ' floaty ' jump behaviour of natural gravity physics. It seems that throughout 28 frames, Mario jumps for 18 frames and then as his jump comes to a descend gravity triples and has a faster fall down.

I thought this might be a similar solution to my game's ' crispy ' movement that rather than gravity affecting the ball's speed, it only determines its trajectory but the speed remains constant for me to change and modify it externally if necessary. However, I can not think of any way to approach this.
