Lesson 2.4.9

Lesson 9 — Newton's First Law of Motion

Get Focused

Newton's first law of motion is foundational to understanding the motion of objects. In this lesson we will investigate Newton's first law and apply it to some real life situations.

Consider the following essential questions as you complete Lesson 9 :

  • What is inertia ?
  • What is the difference between mass and weight ?
  • Does a stationary object have a constant velocity
