- As height rises, velocity falls which results in a reduction of KE and a corresponding rise in PE. At one point KE becomes zero. At that point, velocity becomes zero. This is called the highest point for an upward vertical movement. After this, the ball starts falling downwards.

At the top most point, the velocity is indeed zero. However, it is changing momentarily after that. If the acceleration was zero, the ball would have had no change in velocity and would have stayed up in the air forever.

May 11, 2020 · When we project an object vertically upwards its velocity at maximum height consider to be zero but still, it has acceleration due to gravity i.e $9.8\mathrm{m/s^2}$. But mathematically we know that acceleration is the first derivative of velocity with respect to time $(a=dv/dt)$ .
May 19, 2023 · At the highest point, the object has no kinetic energy where all of its kinetic energy is converted into the potential energy, and therefore the velocity is zero and the object does not accelerate.
Jun 7, 2015 · At a certain point it becomes 0 0. The ball is at 0 0 velocity at that instant (instant is very important). After that the velocity is not strong enough to go against gravity and move up and so loses infront of gravity and begins to obey its words and come down along with it.
At its highest point, the vertical velocity is zero. As the object falls toward Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
Jul 6, 2009 · The acceleration at the highest point of a thrown baseball is indeed 0, as you correctly stated. This is because at the highest point, the velocity of the baseball is momentarily 0 and therefore there is no change in velocity, resulting in an acceleration of 0.
(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
