What are five examples of friction being increased?

Answer 1

~Putting chains on truck tires in the snow

~Rubbing your hands together

~Car Brakes

~Race Cars have special tires to increase traction and friction

~When you walk it's friction that keeps you from sliding all over the place

Answer 2

1. Roughening a surface would increase friction because there is more irregularity for objects to interact with.

2. Increasing the weight of an object would increase friction as it increases the force pushing the surfaces together.

3. Adding more lubricant or reducing the smoothness of surfaces would increase friction as it hinders smooth sliding motion.

4. Increasing the speed at which two surfaces are moving past each other can also increase friction due to dynamic effects.

5. Increasing the contact area between two surfaces would increase friction because there are more points of interaction between the surfaces.
