We use the same equations of motion as before for the constant acceleration problems. However, the acceleration that we use is denoted "g" and is the acceleration due to gravity. Because of this, the motion is purely in the y-direction, which is vertical. Other than these small changes, the problems are solved in a similar way as done previously.
