Is a Ball Tossed Straight Up in Equilibrium at its Brief Moment of Stop?

[vt33]

If a ball is tossed straight up, is it in equilibrium at that brief moment that it comes to a stop before it comes back down?

What is the definition if equilibrium??Static,dynamic and kinetic...

No, the ball is not in equilibrium at that brief moment. Equilibrium refers to a state of balance where all forces acting on an object are equal and opposite, resulting in zero net force. In the case of the ball being tossed straight up, there is still a force acting on the ball due to gravity, causing it to eventually come back down. Therefore, the ball is not in equilibrium at that moment and will only be in equilibrium when it reaches its highest point and momentarily comes to a stop before falling back down.

No, the ball is not in equilibrium at that brief moment. Equilibrium refers to a state where all forces acting on an object are balanced, resulting in a constant velocity or no motion at all. When the ball reaches the highest point of its trajectory and comes to a momentary stop before falling back down, it is still experiencing the force of gravity pulling it towards the ground. Therefore, the forces acting on the ball are not balanced and it is not in equilibrium.
