Worked practice questions

Why does a heavier tennis racquet have the advantage? In a collision what is conserved is:

  1. Force, not momentum
  2. Speed, not mass
  3. Height, not time
  4. Momentum, not force
Show answer and solution

Correct answer: D. Momentum, not force

1. More racquet mass means more momentum. 2. It is momentum, not force, that is conserved. 3. A light softball bat cannot hit a hardball far. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._
