Kinetic friction summary

The video tutorial explains the forces acting on a moving object, including the force opposing motion, gravitational force, and normal force. It highlights the concept of constant friction force, which is empirically shown to be equal to the product of the kinetic coefficient of friction and the normal force. The tutorial provides a foundational understanding of how these forces interact and affect motion.

Define the term 'normal force' in the context of forces acting on an object.
