The discussion centers on the maximum height of a projectile and the forces acting on it during its ascent and descent. Participants clarify that the point where the object is momentarily at rest is known as the "apex" of its trajectory, not a "point of inflection." The primary force acting on the projectile, when neglecting air resistance, is gravity, which causes constant downward acceleration. The Kinematic Equations of Motion for Constant Acceleration are essential for calculating the maximum height of a projectile, particularly when given the total time of flight.

Neglecting air resistance, there is only the force of gravity acting on the thrown object, and its acceleration (downwards) is constant.Jerret Spenst said:
We don't allow speculation or theory development at the PF. We discuss mainstream science, as published in the peer-reviewed literature and mainstream textbooks.Jerret Spenst said:
Why bother trying to introduce an extra force when the whole classical process can be calculated and predicted as accurately as you choose, using the existing classical forces - until you get to the scale of Relativity or QM.Jerret Spenst said:
Are you familiar with the Kinematic Equations of Motion for Constant Acceleration (gravity)?RTM said:
