Iist the material required to verify effect of roughness or frictional force
Answers
Answer:
Heyy !!!
Hopefully this answer will help you out
Explanation:
Friction depends partly on the smoothness of the contacting surfaces, a greater force being needed to move two surfaces past one another if they are rough than if they are smooth.
Answer:
What is the first thing you do when you feel cold? There are two possibilities here: either you cover yourself with a warm blanket or you rub your hands against each other to feel warm. Now, the question is why? How do our hands get warm when we rub them against each other? Well, ‘Friction’ is created by rubbing our hands that generates heat.
Factors Affecting Friction
The force of friction may alter depending on the following factors that affect it:
When two smooth surfaces are in contact, then the degree of friction between them is small because the interlocking between smooth surfaces is less.
When two rough surfaces in contact, then the degree of friction between them is large because the interlocking of between rough surfaces is too much.
It also depends on the weight of the object or on the amount of force applied on the surface by the object.
that's I all know
