Question

what is the vertical acceleration in projectile motion?

Answer 1

Task:

What is the vertical acceleration in projectile motion?

Solution:

The horizontal velocity remains constant during the course of the trajectory and the vertical velocity changes by $9.8\mathrm{m / s}$ every second. 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 $9.8 \, \text{m/s/s}$ , downward and no horizontal acceleration. This is to say that the vertical velocity changes by $9.8 \, \text{m/s}$ each second and the horizontal velocity never changes. 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, gravitational acceleration of $9.8 \, \text{m/s/s}$ .

Answer:

The vertical acceleration in projectile motion is gravitational acceleration of $9.8 \, \text{m/s/s}$
