Lesson 2.4.8

Lesson 8 — A Closer Look at Breaking

Get Focused

When an object accelerates and imbalance of force exists. In this lesson we will look at the causes of acceleration and learn how to calculate the acceleration of an object based on the net force and mass of the object.

Consider the following essential questions as you complete Lesson 8 :

  • What is meant by the term "net force" ?
  • How does the mass of an object affect it's acceleration ?
  • What is the difference between an net force and an applied force
