Answer
When a ball is dropped from a height, neglecting air resistance:
Acceleration: The acceleration of the ball is constant and equal to the acceleration due to gravity (g), which is approximately 9.8 m/s². Its direction is always vertically downwards.
Velocity: The ball starts with an initial velocity of zero (dropped from rest). As it falls, its velocity continuously increases in the downward direction due to the constant downward acceleration. This means its speed increases steadily.
