Homework Statement
If I want to find the difference in velocities of 2 objects A and B
We know the sum of their velocities is A + B
But but is the difference B - A
Why not A - B?
Homework Equations
This is from the equation of calculating restitution where
(greek letter) = (The difference in the velocities after the collision)/(Difference in the velocities before the collision)
The Attempt at a Solution
N/A other than google which didnt help.
