What is the expression for the fractional kinetic energy lost during a collision?
A
f_K = (K_1i - K_1f) / K_1i
B
f_K = K_1f / K_1i
C
f_K = (K_1f + K_1i) / K_1i
D
f_K = K_1i / K_1f
Correct Answer
Option A
Detailed Explanation
The fractional kinetic energy lost is expressed as f_K = (K_1i - K_1f) / K_1i, indicating the loss relative to the initial kinetic energy, as mentioned in the provided context.
