Question

Ann wanted to open a bottle cap and found it difficult, so she used a thick towel which made it easier to open the bottle cap. Explain Why?

Answer 1

Beacuse the surface area of towel is less

Answer 2

• Ann wanted to open a bottle cap and found it difficult, so she used a thick towel which made it easier to open the bottle cap because the rough surface of the towel benefits in increasing friction, and therefore it provides a better grip so the towel, accordingly, makes it easier for her to open the bottle cap.

• Friction is the force that resists the proximate motion of solid surfaces, fluid layers, and material components that slides against each other. There are various types of friction as dry friction is a force that obstructs the relative sideways motion of two solid surfaces in contact. The surface of a towel can be made rough with the help of increasing its thickness; in order to increase friction.
