The ball that was thrown will move until it was hit or caught.
When the batter hits the ball also counts as an unbalance force.
NEWTON'S FIRST LAW OF MOTIONAn object will at rest will remain at rest until acted upon by an unbalanced force
When the catcher catches the ball (unbalanced force) which causes the ball to stay at rest.
NEWTON'S SECOND LAW OF MOTIONThe acceleration of an object is dependent on forces acting on the object and the mass of an object
A baseball has less mass compared to a basketball. When same amount of force is applied to both balls, the baseball would go farther since it is lighter than basketball.
Mass
When the baseball player hits the ball, a force is applied to the bat in the direction toward the batter, while the force applied to the ball in the direction away from the batter.
NEWTON'S THIRD LAW OF MOTIONEvery action has an equal and opposite reaction.
