Answer: kinetic energy
Explanation:
Kinetic energy is the form of energy related to the motion of an object. The kinetic energy of an object is given by:
[tex]K=\frac{1}{2}mv^2[/tex]
where m is the mass of the object and v its speed. Therefore, any object in motion has kinetic energy: in this case, the bowling ball is in motion before the collision, so during the collision it transfers its kinetic energy to the pins.
