The discussion revolves around the concept of projectile motion, specifically focusing on the maximum height of a projectile and the forces acting on it during its ascent and descent. Participants explore definitions, theoretical forces, and the application of kinematic equations in this context.
Participants express differing views on the introduction of theoretical forces, with some advocating for sticking to established classical physics while others wish to explore new ideas. The discussion about calculating maximum height remains open, with no consensus on the specific calculations or outcomes presented.
Some participants reference kinematic equations and established physics principles, while others introduce speculative ideas about forces, leading to a mix of mainstream and theoretical discussions. The conversation reflects a range of familiarity with the subject matter, from basic concepts to more advanced theoretical considerations.
This discussion may be useful for individuals interested in projectile motion, kinematic equations, and the exploration of forces in physics, particularly those looking to refresh their knowledge or engage in theoretical discussions.

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:
