The ONE thing your teacher is NOT telling you that will simply forces!

The video tutorial explains the concept of forces, which are pushes or pulls that can change an object's motion. It covers the SI unit of force, the Newton, and how forces cause acceleration. The tutorial discusses net force, which is the sum of all forces acting on an object, and provides examples of calculating net force. It distinguishes between balanced and unbalanced forces, explaining how they affect motion. The video also introduces natural forces like friction, air resistance, and gravity, highlighting their roles in changing motion. The acceleration due to gravity on Earth is noted as 9.8 m/s².
