Usually because the ball hits in what you could call the weakest part of the bat. If the ball hits directly on a grain, or a weak part of a poorly made bat. the bat will crack. Also, the ball can break the bat at the handle, where the bat is thinnest, due to the massive amount of force the ball is traveling with as it comes in contact with the bat.
Centripetal Force
Definitely gravitational force.
Gravity is the force which makes a thrown ball fall back to the ground. It is the force which attracts all objects to the Earth.

Mechanical weathering occurs when an applied force causes rock to break.
Definitely gravitational force.
just like the sweet spot is the strongest part of the bat the grain is the weakest part so when a massive amount of force is implied the bat can break.
Friction?
The force of gravity.
The contact force will keep the ball moving but as the ball goes farther the ball slows down that's were the non contact force comes in it makes the ball not in contact
There is more force behind the egg thrown further distance than the egg thrown from small distance. That and gravity acceleration.
There are a multitude of variable that need to be taken insto consideration. For each, How much force is being put into the swing or throw?? For The batted ball, it depends of the angle of which it strikes the bat. For the thrown, If there is the same force exerted on the ball as the batted ball, it will have half of the velocity. But, all variables considered, a typical batted ball travels with more force and velocity (Speed) than one thrown.
A force is when there is an automatic out at the base if the ball is thrown there
The force that causes rocks to break as plates rub past each other is called shear stress. This stress leads to the formation of faults and the subsequent release of energy in the form of earthquakes.
Gravity is the force which makes a thrown ball fall back to the ground. It is the force which attracts all objects to the Earth.
