Lesson 4 Identifying perpendicular distance and understanding how Levers work

This is the fourth lesson of the course "Turning Effect of a Force", designed for Secondary 3 and 4 students or High School students in Grade 9 or 10. In this video, you will learn how to identify the perpendicular distance (in challenging questions and in Levers) to use in the formula for finding the Moment or Turning Effect of a Force.
