How does vertical velocity work

For any calculations involving the projectile's horizontal motion, we use. Projectiles - vertical motion. The vertical motion of a projectile is controlled by the force of gravity. This means that there is an unbalanced force acting on the ball and so the ball will accelerate downwards. These same two concepts could be depicted by a table illustrating how the x- and y-component of the velocity vary with time. The numerical information in both the diagram and the table above illustrate identical points - a projectile has a vertical acceleration of 9.

This is to say that the vertical velocity changes by 9. This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force. A vertical force causes a vertical acceleration - in this case, an acceleration of 9. But what if the projectile is launched upward at an angle to the horizontal?

How would the horizontal and vertical velocity values change with time? How would the numerical values differ from the previously shown diagram for a horizontally launched projectile?

The diagram below reveals the answers to these questions. The diagram depicts an object launched upward with a velocity of For such an initial velocity, the object would initially be moving These values are x- and y- components of the initial velocity and will be discussed in more detail in the next part of this lesson.

Again, the important concept depicted in the above diagram is that the horizontal velocity remains constant during the course of the trajectory and the vertical velocity changes by 9.

The numerical information in both the diagram and the table above further illustrate the two key principles of projectile motion - there is a horizontal velocity that is constant and a vertical velocity that changes by 9.

As the projectile rises towards its peak, it is slowing down Launching and landing on different elevations. Total displacement for projectile. Total final velocity for projectile.
