MLB Rule 2 defines a foul ball and includes the following ...
"A batted ball not touched by a fielder, which hits the pitchers rubber and rebounds into foul territory, between home and first, or between home and third base is a foul ball."
It is a ground ball.
It's just called a ground ball.
No, it is simply a ground ball and is in play.
A batted ball that hits the pitcher's mound (or any base) is considered a fair ball. A fair ball that lands out of play is considered a ground rule double.
The potential energy of the rubber ball is converted into kinetic energy as it falls. When the ball hits the ground, some of the energy is absorbed by the ball and the ground, while the rest is converted to other forms such as sound and heat.
A leather basketball is better than a rubber ball but if your playing outside the ground ruins the leather so a rubber ball is better when you are playing outside
The pitcher
A soccer ball bounces due to the elasticity of the material it is made from, typically rubber. When the ball hits the ground, the rubber compresses and stores energy. This energy is then released, causing the ball to bounce back up in the opposite direction.
When a rubber ball is dropped from a height, it accelerates downwards due to gravity. As it falls, the ball's potential energy is converted into kinetic energy. Upon impact with the ground, the kinetic energy is transferred back into potential energy through deformation of the rubber material, causing the ball to bounce back up.
If a baserunner is in foul ground and is hit by a batted ball, the ball is declared foul and all runners return to their previously occupied base, regardless of whether or not the runner that was hit was standing on the base.
The ball will accelerate downwards at a rate of 9.8 m/s^2 due to gravity. As the ball falls, its velocity will increase, reaching a maximum at the point of impact with the ground. The rubber ball will bounce back up after hitting the ground but not to the same height as it was initially thrown from.
When a rubber ball is dropped, the potential energy is converted to kinetic energy upon hitting the ground, causing the ball to compress and then rebound. The elastic properties of the rubber material then allow the ball to quickly return to its original shape, transferring the kinetic energy back into potential energy and causing the ball to bounce back up.
