Introduction to Forces and Categories of Forces

The video introduces the concept of forces, defining them as interactions that cause a push or pull on objects. It categorizes forces into contact and non-contact types, explaining each with examples. Contact forces include friction, tension, air resistance, and normal force, while non-contact forces cover gravity, magnetic, and electrostatic forces. The video also provides examples to illustrate these concepts and discusses the units of force, emphasizing that force is a vector quantity with both magnitude and direction.
