When an object is thrown or propelled upwards and it meets the point at deceleration and drops; what is that point called, where the object is not moving in either direction?
Welcome to the PF.Jerret Spenst said:When an object is thrown or propelled upwards and it meets the point at deceleration and drops; what is that point called, where the object is not moving in either direction?
Neglecting air resistance, there is only the force of gravity acting on the thrown object, and its acceleration (downwards) is constant.Jerret Spenst said:Thank you! Now in that state, could you propose that there would be a new force acting on the object or even the loss of one.
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:True, but I'd like to discuss the possibility of theoretical forces not yet discovered or applied to general physics.
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:True, but I'd like to discuss the possibility of theoretical forces not yet discovered or applied to general physics.
Are you familiar with the Kinematic Equations of Motion for Constant Acceleration (gravity)?RTM said:If an object is propelled straight up from ground level, and is unaffected by wind or other forces, and it takes say, 4.6 seconds for it land back down, can it's max height be calculated? If so, what's the answer and math? Thanks!
The formula for calculating the maximum height of a projectile is h = (v^2 * sin^2(theta)) / (2 * g), where h is the maximum height, v is the initial velocity, theta is the angle of launch, and g is the acceleration due to gravity.
Air resistance can decrease the maximum height of a projectile by slowing it down and reducing its overall velocity. This results in a shorter flight time and a lower maximum height.
Gravity is the main factor that determines the maximum height of a projectile. As the projectile travels upwards, gravity slows it down until it eventually reaches its maximum height and begins to fall back to the ground.
Yes, the maximum height of a projectile can be greater than the initial height as long as the angle of launch is not 90 degrees and there is no air resistance present.
Changing the angle of launch can significantly affect the maximum height of a projectile. A launch angle of 45 degrees will result in the maximum height, while any angle greater or less than 45 degrees will result in a shorter maximum height.
