Worked practice questions

Earth's rotation is slow enough that Earth is nearly a:

  1. Rotating frame
  2. Fictitious frame
  3. Non-inertial frame
  4. Inertial frame
Show answer and solution

Correct answer: D. Inertial frame

1. In an inertial frame all forces are real. 2. Earth is nearly inertial. 3. Weather systems still show slight effects. _Source: OpenStax College Physics for AP Courses 2e, Chapter 4, Dynamics: Force and Newton's Laws of Motion (CC BY 4.0)._
