Free fall
A ball just dropped is an example of free fall, where the only force acting on it is gravity causing it to accelerate downwards at a constant rate of 9.81 m/s^2.
A rock that is dropped, and a apple falling from a tree.Hold a ball in your hand, stretch out your arm, and drop the ball. As it is moving towards the ground, it is in free fall.
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
The height from which the ball is dropped is the independent variable, as it is what is being manipulated. The height of the ball's bounce is the dependent variable, as it is what is being measured and is affected by the height from which the ball is dropped.
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.

The operative word was dropped in the sentence, fragmenting it severely. I just dropped in to say hello. Dick dropped Jane's ball.

If the player catching the ball has control of it and then he drops it it is a fumble, if they never caught it but they just touched it it is an incomplete pass
The factors that affect the bounce of a dropped ball include...... the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're on ; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces.
Yes - the greater the height an item dropped the resulting bounce is higher
