The completed table is given below:
| Situation | Is the Friction Caused Advantageous or Disadvantageous? | Method of Increasing or Decreasing Friction |
|---|---|---|
| The car keeps slipping when parked in the driveway | Disadvantageous | Increase friction between the wheels and brake shoe by using handbrakes |
| The sole of a shoe has worn out | Disadvantageous | Increase friction by repairing/replacing the shoes with new soles or using shoes with treads |
| A person is able to run on a treadmill | Advantageous | No change needed/Increase friction if slippery by wearing proper sports shoes |
| The chart paper in your classroom is stuck to the wall | Advantageous | No change needed / If needed, increase friction using glue, tape or pins |
