That's the explanation I was looking for. Thanks a lot for clearing that up. It's first year physics, so I wanted to make sure that I was getting the fundamentals right.
What do you mean "act of throwing is complete"? If you mean when the ball is on its way back down, then the acceleration is still positive, it's just in another direction. In a motion diagram the arrows for velocity and acceleraton will all point in the same direction for the ball on its way...
Hi everyone,
I was just reading a physics textbook when I noticed something. The motion diagram shows that if a ball is thrown upward into the air, the acceleration is always the opposite of the velocity. Wouldn't the acceleration initially have to be in the same direction as the velocity? How...
