Newton's Law #1: When you bowl the ball, it pretty much goes in a straight line. There is a little bit of friction.
Newton's Law #2: As the ball hits the pins, it applies a force proportional to the mass of the ball and its acceleration.
Newton's Law #3. As the ball hits the pins, they make the ball shift slightly off course.

There is rotational friction in the ball, and static friction with the pins.

The bowler adds kinetic and potential (if they drop the ball instead of rolling it) energy to the ball. The ball has kinetic energy (that is why it is moving). Then the kinetic energy is transferred to the pins, which makes them go every which way, unless you are a really bad bowler.
