Activities that are made difficult by friction:

1. Friction generates heat in the machines which leads in the wastage of energy
2. Noise is produced in the machines due to friction
3. Forest fires occur due to the friction present in between the branches of trees
4. Friction opposes motion
5. The efficiency of the machine will be decreased due to friction
6. To avoid friction, lubricants should be applied to machine parts which costs more money
7. Friction causes unwanted heat in machine parts
8. Due to friction, the machine consumes a lot of fuel
9. Machine parts can wear out rapidly due to friction
10. Extra friction can make it difficult to walk
