Forces: Gravity and Magnetism Concepts

The video tutorial explains the concept of forces using a swing as an example. It introduces gravity as an invisible force that pulls objects toward Earth and compares it with magnetic force, which acts on specific materials. The differences between gravity and magnetic force are highlighted, and the video concludes with a recap and real-world application of these forces.
