Coefficient of restitution
e = (v₂ − v₁)/(u₁ − u₂)
Where: e = electron charge (C) / coefficient of restitution, u₁ = initial velocity 1 (m/s), u₂ = initial velocity 2 (m/s), v₁ = final velocity 1 (m/s), v₂ = final velocity 2 (m/s)
Solved example
Given: u_1 = 7, u_2 = 5, v_1 = 10, v_2 = 4
Find: e (electron charge (C) / coefficient of restitution)
- Formula: e = (-v₁ + v₂)/(u₁ - u₂)
- Substitute the values: e = (-10 + 4)/(-5 + 7)
- Result: e = -3
Answer: e = -3
