AI Thread Summary
An object thrown vertically decreases in speed until its velocity reaches zero due to the force of gravity acting against its upward motion. If an object is thrown upwards, then it will decelerate because gravity exerts a downward force that opposes its initial velocity. This deceleration continues until the object's upward velocity is completely countered by gravity, resulting in a momentary stop at the peak of its trajectory. The discussion emphasizes understanding the role of gravitational force in this process. Ultimately, the interplay of forces determines the object's change in speed until it halts.

I'm currently in the process of writing a practical report and am wondering whether any can explain to me why an object will decrease in speed until its velocity is 0

Preferably in an if... then... because... statement.

Hi there
welcome to PF :smile:

why do you think it does ?
what forces do you think are acting on the object ?Dave
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
