The vertical axis shows the ball’s velocity, the horizontal axis represents time, and the blue curve shows the ball’s velocity over time. As soon as the ball is thrown upwards, its velocity will reduce because of the gravitational pull. Since its acceleration is constant, -9.81 m/s², the velocity curve will be a straight line.
1) When a ball is thrown up and it comes down When the ball leaves the hand, there is no upward force acting on the ball. The only force acting on the ball is its weight. This net force is opposite to the motion of the ball, hence causing the ball to decelerates. Refer to this post for the explanation (comics)
The three equations, written for motion in the y-direction, are: 1. y = y 0 + v 0 Δt + ½ a(Δt) 2 (relates position and time) 2. v = v 0 + aΔt (relates velocity and time) 3. v 2 = v 0 2 + 2a(Δy) (relates velocity and position) These equations only apply for periods of motion in which acceleration is constant!

The higher spin rate generally means more break on the pitch; that is, more movement side-to-side or up-and-down. Real Life Example: All pitches fall due to gravity as they approach the plate, but fastballs don’t fall as much because of backspin and curveballs fall even more than expected because of top spin.

An object’s velocity is constant only if its speed and direction don’t change. Therefore, constant velocity is always along a straight line. An object’s velocity will change if either its speed or direction changes. For example, if a bus traveling at 15 m/s south speeds up to 20 m/s, a change in velocity has occurred.
Reading velocity-time graphs The motions of five runners are shown in Figure 6. Assume that the positive direction is east. The slopes of Graphs A and E are zero. Thus, the accelerations are zero. Both graphs show motion at a constant velocity—Graph A to the east and Graph E to the west. Graph B shows motion with a positive velocity eastward.
So, this is zero degrees on up to 90 degrees. That choice of angle at which to throw the ball has a big effect on the ball's path. It, it determines both how long the ball stays above the ground and how far it travels down field during its time aloft. Let's start by throwing the ball straight up. That is, 90 degrees above the horizontal.
