GCSE Physics - Resultant Forces & Free Body Diagrams #42

The video tutorial explains how to use free-body diagrams to find the resultant force on an object. It describes how to represent forces acting on an object using arrows, with an example of a plane in flight. The tutorial covers how to calculate the resultant force by considering the magnitude and direction of each force, and provides examples of vertical and horizontal force components. It concludes with a scenario where forces are balanced, resulting in equilibrium.

How would the resultant force change if the air resistance increased to 120,000 newtons?

What does it mean for an object to be in equilibrium in terms of forces?
