Force and Newton's Laws: Newton's First Law of Motion

The video tutorial explains Isaac Newton's laws of motion, focusing on the first law. It describes how objects in motion stay in motion and objects at rest stay at rest unless acted upon by an external force, with friction being a common force. The concept of inertia is introduced, explaining how it affects motion and why safety belts are important in vehicles.

Define inertia and explain its significance in motion.

How does mass affect an object's inertia and its motion?
