May 05, 2015· When a baseball is thrown or hit, the resulting motion of the ball is determined by Newton's laws of motion.From Newton's first law, we know that the moving ball will stay in motion in a straight line unless acted on by external forces.A force may be thought of as a push or pull in a specific direction; a force is a vector quantity.

Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this. Collisions involve forces (there is a change in velocity). The magnitude of the velocity difference just before impact is called the closing speed.
