Question 53

(Forces and Changes in Motion)

Andrew is at the bowling alley and is about to roll the ball down the lane. With the bowling ball in his hand, he swings his arm forward and releases the ball. The ball then rolls down the lane to the end and knocks down the pins. Describe the forces acting on the pins before and as the ball hits them.

Accepted Answer

Before the ball hits the pins, the forces acting on the pins are balanced. The force of gravity is pulling down on the pins, but the floor is pushing up on them. When the ball hits the pins, the force of the bowling ball pushes the pins, overcoming the forces that had

been balanced. The pins were acted on by the force of the ball and their motion changed.

Answer

The pins have balanced forces and are not moving. The ball is moving forward at a constant rate of speed, so its forces are also balanced. When two objects with balanced forces meet, their forces become unbalanced. This causes the pins to fall over and roll around.
