Exploring Balanced and Unbalanced Forces

The video tutorial explains Newton's first law of motion, focusing on balanced and unbalanced forces. It uses the example of a horse to illustrate how forces like gravity and reaction force balance each other, resulting in no acceleration. The tutorial further discusses how driving force, friction, and air resistance interact to maintain constant velocity or cause acceleration when unbalanced.

Who formulated the three laws of motion?

• Galileo Galilei

• Isaac Newton

• Albert Einstein

• Nikola Tesla
