Net Force and Equilibrium

How do I calculate the net force?

In this post, we explore the concept of net force and equilibrium in one-dimensional and simple two-dimensional contexts, as a part of the Prelim Physics course under the module Dynamics and sub-part Forces. To calculate the net force, we use:

  • Algebraic addition
  • Vector addition
  • Vector addition by resolution into components

 

In the following four videos, the topic of net force and equilibrium are covered, showing you how to determine the net force and equilibrium using the addition of vectors, graphically and algebraically.

Part 1: Algebraic Addition

 

Part 2: Parallelogram Method

 

Part 3: Net force and equilibrium

 

Part 4: Inclined plane introduction
