Answer:
friction is a force which oppose the motion of other object
friction is always work opposite the direction of motion of object
ex- without friction bike tired is not stopped
SI unit = Newton = 1kg .m.
fluid friction described the friction between the two layers of liquid which is relative to each other
I hope it is useful for you

Answer:
answer no 1- Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult. Friction always works in the direction opposite to the direction in which the object is moving, or trying to move.
- example, if book is kept on floor and the book moves with respect to the floor. It is the frictional force between two surfaces that are rubbing against each other.
answer no 2-As an example, ice on steel has a low coefficient of friction – the two materials slide past each other easily – while rubber on pavement has a high coefficient of friction – the materials do not slide past each other easily. The coefficients of friction ranges from near 0 to greater than 1.
answer no 3-Riding a bike. A seagull soaring through the air. Air resistance is an example of fluid friction caused by the particles that make up air. It causes a falling object to slow down.
