Understanding Forces

The video tutorial introduces the concept of force as a push or pull that can cause an object to move, change shape, or alter its speed and direction. It provides examples from daily life, such as playing tug of war, kicking a ball, and using machines like fans and cranes. The video also explores how forces can be exerted without direct contact, such as through battery-operated devices and natural phenomena like earthquakes and cyclones.
