Physics Introduction to Statics and Dynamics: Forces and Newton's Laws - Field Forces

This video tutorial explores the concept of field forces in physics, emphasizing that forces are interactions between objects rather than inherent properties. It covers gravitational, electric, magnetic, weak nuclear, and strong nuclear forces, explaining their characteristics and differences. The tutorial also distinguishes between mass and weight, highlighting their unique definitions in physics. Through examples and scenarios, the video illustrates how these forces operate without physical contact, mediated by fields. The lesson concludes with a summary of the key concepts discussed.
