Help answer this question below.
It immediately begins to slow down.
There is nothing on the ball itself to create thrust...no rocket engine...no spinning fan-blades...nothing.
Force stops being applied to the ball once it leaves the hand of the pitcher, and is subject only to opposing forces, like friction and gravity.
It starts to slow down the moment it is released.

In the OCR GCSE History course, if I got a B for the coursework, could I still get an A or A* and how well in I'd need to do in the tests?

You're reading Is a baseball thrown by a pitcher, faster when it leaves the hand because of thrust?..or...does it immediately begin to slow down due to friction?

Gravity does not slow the ball down, but you are right, the ball is subject to gravitational force. :)

I didn't mean to imply that it slows the ball...only that it is a force that it is affected by. Thank you for pointing out the distinction so that it is not misinterpreted.

I guessed that is what you meant, but it was not 100% clear (to me at least lol).
We could also go one step further and say that the air resistance (friction) also counters the force of gravity. But I Suppose if we really want to get into this we would need to include the heat increase of the ball due to the friction too.
Dont you just love how complicated "simple" physics can be lol
