AI Thread Summary
When a ball is thrown, the force from the thrower’s hand only acts on the ball during the initial motion. Once the ball is many meters away, the hand's force no longer influences it, as the force was only necessary to initiate the motion. This distinction highlights a key difference between Newtonian and Aristotelian mechanics, where motion continues without the need for ongoing force. The ball continues to move due to its inertia, not because of any remaining force from the throw. Understanding this principle clarifies the nature of forces and motion in physics.

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.

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
