Ways to increase friction :
1. On a rainy day, we throw some sand on the slippery ground. This increases friction between our feet and the ground. The chances of slipping reduce.
2. Similarly, sand is spread on tracks covered with snow. Force of friction between the wheels and the track increases and driving becomes safer.
