Question

For a partially elastic collision (0 < e < 1), which of these is true?
  1. A
    KE is conserved
  2. B
    KE is lost (some)
    Correct
  3. C
    KE increases
  4. D
    Momentum is not conserved

Correct answer

KE is lost (some)

Explanation

Partial elasticity: e between 0 and 1. Some KE is lost (deformation, heat) but momentum is still conserved.
