SUMMARY

The force exerted by your hand on a thrown ball ceases to act once the ball is released, regardless of the distance it travels. This principle is rooted in Newtonian mechanics, which states that a force is required to change an object's motion, not to maintain it. The ball continues to move due to its initial velocity imparted by the throw, not because of any ongoing force from the hand. This distinction clarifies the difference between Newtonian and Aristotelian mechanics.

PREREQUISITES
  • Understanding of Newton's Laws of Motion
  • Basic knowledge of kinematics
  • Familiarity with the concepts of force and motion
  • Awareness of Aristotelian vs. Newtonian physics
NEXT STEPS
  • Study Newton's First Law of Motion in detail
  • Explore kinematic equations for projectile motion
  • Investigate the historical context of Aristotelian physics
  • Review examples of force and motion in real-world scenarios
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in the foundational principles of motion and force.

Homework Statement


You throw a ball. When the ball is many meters away from you, is the force of your hand still acting on the ball?

2. The attempt at a solution
My thoughts are:
No because it's many meters away.
Yes because it's still moving from the throw.

I have no idea which is right :(

The answer is no. The force exerted by your hand was necessary to cause a change in motion, but not necessary for motion itself. This point was the fundamental difference between Newtonian and Aristotelian mechanics.
 


Ace, thanks.
