If you roll a ball up a hill it undergoes negative upward and positive downward acceleration.
The speed of the ball will increase at the bottom of the slope due to the conversion of potential energy into kinetic energy as it rolls downhill. Assuming no external forces are acting on the ball, it will be traveling at its maximum speed at the bottom of the slope.
Not necessarily. If it's rolling in a straight line on a smooth and level floor, then the acceleration is as good as zero. But if the ball is rolling up a hill, or down a hill, or around the groove in a roulette wheel, or through grass and slowing down, then there's substantial acceleration.
The speed of the ball will change as it rolls down an irregular slope due to the varying slope angles and surface conditions affecting its motion. The acceleration of the ball will also change accordingly as it encounters different levels of resistance and gravitational forces from the irregular slope.
A ball rolls faster on a steeper ramp because gravity has a greater component pulling the ball downhill, increasing its acceleration. On a less steep ramp, the gravitational force component is smaller, resulting in slower acceleration and lower speed for the ball.
The speed of a freely falling ball would increase by approximately 9.8 m/s every second due to gravity. This acceleration of 9.8 m/s^2 is the acceleration due to gravity on Earth.
It's 9.81m/s since vertical acceleration is always constant.

Once a ball has fallen a distance through the air, and it contacts the ground, its speed will rapidly decrease until it has stopped moving. The acceleration experienced by the ball is so great that it seems to stop instantly. Most likely, it will bounce back up, and then repeat this cycle a few times before coming to rest.

Average acceleration during a time interval = (change in speed) divided by (time for the change) =(25) / (5) = 5 meters per second2

The velocity of a ball rolling down a hill will increase due to the acceleration caused by the pull of gravity. As the ball gains speed, its velocity will continue to increase until it reaches the bottom of the hill.
The ball thrown straight down from a bridge will experience an acceleration due to gravity. On Earth, this acceleration is approximately 9.81 m/s^2 and acts in the downward direction. The acceleration will cause the ball to increase in speed as it falls towards the ground.
Forces help speed up a ball by providing it with acceleration, which is the rate of change of velocity. When a force is applied to a ball, it overcomes any resistance, such as friction, allowing the ball to move faster. The force increases the ball's momentum, resulting in an increase in speed.
As the ball falls farther below the point of release, its velocity will increase. This is due to the acceleration caused by gravity pulling the ball downward. The acceleration will cause the ball to speed up as it falls.
