The discussion centers on the forces acting on a ball thrown with an initial velocity \( v_0 \) as it follows a projectile motion, specifically questioning the presence and value of any force in the x direction while acknowledging the force in the y direction due to gravity.
Participants express differing views on the existence of a force in the x direction, with some asserting that no force is present while others question the initial conditions of the throw. The discussion remains unresolved regarding the nature of forces in the x direction.
The discussion does not clarify the assumptions regarding the initial conditions of the throw or the definitions of "throw" versus "release," which may influence the interpretations of the forces involved.
More critically, what would be the direction of such a force?annamal said:If we throw a ball with initial velocity v0, and the ball progresses in a projectile motion, ignoring air resistance, will there be a force in the x direction? If so, what is that force in the x direction's value mathematically?
That's not much of a "throw". You are just releasing the ball, which will fall straight down.annamal said:If we throw a ball with initial velocity v0
