Title: A ball climb up another object on a frictionless surface Post by: Fu-Kwun Hwang on February 25, 2007, 01:21:59 pm Because there is no friction between objects and between object and the ground.
The total momentum in the horizontal direction must be conserved. Try with different initial velocity and water how the motion changed! The total energy of the system is always conserved,too!
