A ball rolls on a very smooth horizontal surface and keeps moving for a long distance before stopping. According to Galileo, the ball stops mainly because of what reason?

Aristotelian and Galilean Views on Vertical Motion 1.Aristotle believed that heavier objects fall faster than lighter ones. 2.Galileo concluded that objects fall with the same acceleration in the absence of air resistance.

Galileo’s Inclined Plane Experiments 1.Galileo used inclined planes to slow down motion for easier measurement. 2.Galileo used inclined planes to prove that gravity does not affect motion.

Falling Objects in a Vacuum 1.Galileo inferred that in a vacuum, all objects fall at the same rate. 2.Galileo directly tested falling objects in a perfect vacuum.

Aristotelian Explanation of Projectile Motion 1.Aristotle believed projectile motion occurs in two stages. 2.Aristotle explained projectile motion as a parabolic path.

Galilean Explanation of Projectile Motion 1.Galileo explained projectile motion as a combination of horizontal and vertical motions. 2.Galileo concluded that horizontal motion has constant velocity when friction is absent.

Concept of Inertia 1.Galileo recognized that motion can continue without applied force. 2.Galileo formally defined inertia as a universal law of motion.

Newton’s First Law of Motion 1.Newton’s First Law states that a net force is required to change motion. 2.Newton’s First Law applies only to horizontal motion.

Distinction Between Galileo and Newton 1.Galileo’s assertion on motion was qualitative and limited in scope. 2. Newton generalized Galileo’s ideas into a universal law.

Application in Real-Life Context 1.A spacecraft in deep space can continue moving without engine thrust. 2.This situation is explained by Newton’s First Law of Motion.
