When more than one object and its surface come in contact with each other, a force is created that resists the motion and that force is called friction. It reduces the output to input ratio and the machine’s mechanical advantage. Energy used by an automobile to limit the friction is one quarter. The friction present in the tires and the clutch allows the car to stay on the ground and drive.
Friction is a vital phenomenon in the world of physics and a crucial subject in schools and professional colleges.

Various Type of Frictions One Should Know
Static friction, rolling friction, sliding friction, and fluid friction are the four types of friction. Sliding, rolling and static ones happen between solid surfaces, whereas the fluid one takes place between gases and liquids. All the four friction types are discussed below,
- Static friction – objects that are resting on the ground or the surface, for instance, your foot on the road. This friction helps us to walk without slipping. It is difficult to walk on the ice as it has less friction making us slip on it.
- Sliding friction – when objects are sliding on a surface the force that acts on them is the sliding friction. It is weaker than the static one. For example, we write on the paper with the lead of the pencil in a sliding position so that the pencil leaves a mark on the paper, which is sliding friction.
- Rolling friction – when objects roll on the surface then rolling friction works on them. It is the weakest among the above two.
- Fluid friction – for the objects moving by a fluid, something that can take a container’s shape and flow. For instance, when you move your body in the water you feel resistance from the water. When a parachute lands on the ground from the top, it even experiences resistance from the air that slows down its movement. The more the size and speed of the object the more is the friction experienced.
What are the factors that affect it?
Enlisted below are a few of the factors that affect the force of friction, read below
- The texture of the surface and the compelling force’s amount between them
- The friction force’s amount is affected by the object’s position and angle
- When the two objects are placed flat against each other, then the object’s weight will be similar to the force of friction
- Friction force becomes more than the object’s weight and it rises when an object is moved against the surface.
The subject may look complicated but it becomes very fascinating once you get a deep understanding of it.
