Question

definition of friction and types of friction​

Answer 1

Answer:

Friction is the force that opposes motion between any surfaces that are in contact. The reason we are able to control cars at all is because of friction between the car's tires and the road: more accurately, because there are three kinds of friction: rolling friction, starting friction, and sliding friction.

Answer 2

$\large \fbox{Friction:}$

➻ Friction is defined as the force that opposes the motion of a solid object over another. 

$\large\fbox{Types of Friction:}$

➻ Following are the friction types which depend on the types of motion:

• Static Friction
• Sliding Friction
• Rolling Friction
• Fluid Friction

Static Friction: Static friction is defined as the frictional force that acts between the surfaces when they are at rest with respect to each other.

Sliding Friction: Sliding friction is defined as the resistance that is created between any two objects when they are sliding against each other.

Rolling Friction: Rolling friction is defined as the force which resists the motion of a ball or wheel and is the weakest types of friction.

Fluid Friction: Fluid friction is defined as the friction that exists between the layers of the fluid when they are moving relative to each other.
