Force and Newton's Laws: Gravity and Falling Objects

The video explains the principle of gravity through Galileo's famous experiment with cannonballs, demonstrating that objects of different masses fall at the same rate. It further illustrates this concept using rocks and discusses the constant acceleration due to gravity, which is 9.8 m/s². The video also covers how an object's velocity increases as it falls until it reaches terminal velocity, where it no longer accelerates.

What did Galileo demonstrate with his experiment involving cannonballs?

How did Galileo's findings challenge the understanding of mass and falling objects?

Explain the significance of the acceleration due to gravity being 9.8 meters per second squared.

What happens to the velocity of an object as it falls?

Describe what terminal velocity is and when it occurs.
