Maybe I should start a new thread but I was also wondering about the conservation of energy upon collision between ball and floor. The ball will lose energy due to heat, sound and friction at least, but how does the type of surface influence these energy losses? I know hard surfaces tend to...
Sorry putting it into words is pretty confusing for me. I know that it's sqrt(2gh/2gH) which is derived from mgh=1/2mv^2, so I guess COR is the ratio of the square root of the velocities, seeing as v=sqrt(2gh). Unless you mean it's the ratio of the square root of the heights?
Homework Statement
I'm trying to find the coefficient of restitution (COR) and energy loss upon impact of a bouncing ball, and I'm trying to understand how these relate to each other.
Homework Equations
COR=sqrt(2gh/2gH)
suvat equations (possibly)
1/2mv^2=mgH (using m=0.0585kg, g=9.8)
energy...
