Question

5. Define static friction ?
6. Why it is difficult to move on a wet floor ?
7. Give two examples of static friction​

Answer 1

Answer:

5.)Static friction is the friction that exists between a stationary object and the surface on which it's resting. Once the objects have already started moving, kinetic friction takes over. This is the friction that exists between two objects moving relative to each other.

6.)It is difficult to walk on a wet floor because layer of water makes floor smooth. The coating of water reduces the friction and the foot cannot make a proper grip on the floor and it starts getting to slip on the floor.

7.)Examples of this type of friction includes: You are standing in a moving bus, holding on to the cylindrical hand railing on top. The driver suddenly brakes.
