well, i fixed that... and it still doesn't work... its probably how I am calculating the new x and y velocities... idk tho...

I'm having a bit of a problem with physics calculation for a bouncy ball program I am creating in java. I've been java programming for almost three years, and excelled in my class, but when it comes to physics for java games and what not, I am totally useless. Heres the problem: a Ball, when put...

well, i mean for the earth... he says that on the earth, it has to be negative to go downward. i was using the whole coordinate system thing to explain it better to him because he's also a java programmer. And yes, acceleration of gravity as defined below, which i also showed him. I mean, do u...

What u can do is after detection of collisions, reverse the velocities. I've also seen one instance of swapping the two balls velocities... so that the faster balls velocity gets transferred over and vice versa.

Me and my friend have been arguing about the coordinate system used for the earth... specifically gravity. he's trying to tell me the value of gravity is -9.8ms/2, when I've read from several books and other online resources that's it 9.8ms/2... a positive number. Hes keeps going on and on and...
