The bowler should choose a ball with more mass or throw the ball with more force.
The bowler should choose a ball with less mass or throw the ball with more force.
The bowler should choose a ball with more mass or throw the ball with less force.
The bowler should choose a ball with less mass or throw the ball with less force.

Answer 1

What would cause the momentum of a moving object to increase?

A force acting in the direction opposite the object’s motion is removed from the object.
Two forces of equal magnitude act on the object in opposite directions.
A force acting in the direction of the object’s motion is removed from the object.
A new force acts on the object, opposing the object’s motion.

Answer 2

To maximize the chances of knocking down all the pins, the bowler should focus on using a ball that creates a greater impact on the pins. According to Newton's second law of motion (F = ma), increasing the force applied to the ball (by throwing it harder) directly increases its acceleration.

1. **Using a ball with more mass** will indeed increase the momentum and impact force when it strikes the pins, potentially leading to a better chance of knocking them all down.
2. **Throwing the ball with more force** will increase its acceleration, thereby increasing the impact force when it hits the pins.

Thus, the best choice is:

**The bowler should choose a ball with more mass or throw the ball with more force.**
