i think its compression and ... sorry i don't know the other one
The two forces that cause a moving ball to slow (if it is rolling on the ground) are air resistance and friction with the ground.
Because of the forces that act on the ball in the direction opposite to its motion ... air resistance and friction with the floor.
The two forces that act on the ball after it leaves your hand are gravity and air resistance.
The force that acts on a ball when in the air is gravity.
You get frictional force. That is because when the tennis ball furr and the grass rubs together you et friction.
Gravity brings it down. Air resistance will act the opposite way, this will be tiny at first but will increase with the balls velocity.

The force that acts on a ball when in the air is gravity.
The action and reaction forces act on different objects. For two forces to cancel each other - and provide a net force of zero, for Newton's First Law - they must act on the same object.
BECAUSE THE FORCES AREN'T EQUAL IF THEY WERE THE BALL WOULD FALL STRAIT DOWN. the bat (even if it were lighter than the ball) has more inertia/energy which cancels out the kinetic energy of the ball, the residual kinectic energy of the bat that isn't canceled out changes the direction of the ball, the more direct the angle the more effective and further the ball will go
Kinetic energy, momentum, gravity.
Gravity, Air resistence, friction and the push from the floor/table

It does act upon it. If gravity weren't acting upon the ball, it would float into the air instead of remaining on the alley floor.
Gravity brings it down. Air resistance will act the opposite way, this will be tiny at first but will increase with the balls velocity.
1). gravitational attraction between you and the earth 2). upward "normal" force exerted by the floor on the bottom of your feet These are the same forces that act on you while you're standing on anything, whether it's moving or not.
Forces don't act on other forces - forces act on objects.
