Question

Which force would have the least effect on a bowling ball rolling down a lane toward bowling pins? Explain. 1. gravity 2. friction 3. air resistance 4. magnetism

Answer 1

Among the forces listed, **magnetism** would have the least effect on a bowling ball rolling down a lane toward bowling pins.

### Explanation:

1. **Gravity**: This force pulls the bowling ball downwards and is a significant factor in keeping the ball on the lane and determining its weight.

2. **Friction**: This force acts between the ball and the lane's surface. Friction is crucial because it allows the ball to roll without slipping and affects its speed and direction.

3. **Air Resistance**: While air resistance does exert a force on the bowling ball, it is relatively small compared to gravity and friction. However, it can slow the ball down slightly as it rolls.

4. **Magnetism**: Unless the bowling ball or the pins are made from magnetic materials or are influenced by a strong external magnetic field, magnetism would have minimal impact on the motion of the ball down the lane. In typical bowling conditions, where the ball is made of a non-magnetic material like urethane or polyester, magnetism does not play a significant role.

Thus, in the context of a standard bowling scenario, magnetism is the least relevant force affecting the motion of the bowling ball.
