Friction on an inclined plane is common. Objects can have frictional forces on an inclined plane as well as a straight one. Friction like this is in our lives.
You need to know that friction is one of the important forces in life. This force contributes to the state of balance of an object.
The size of the frictional force is influenced by the degree of roughness of the object itself. The friction coefficient is divided into two types, namely static friction and kinetic friction.
In this discussion, we will discuss more about the viscous forces that exist on the inclined plane.

The Occurrence of Friction on an Inclined Plane
Whether you realize it or not, this friction or frictional force is a phenomenon that occurs every day. Maybe you are also quite familiar with this one style.
In fact, every day you experience or do friction. For example, like you walk and also run.
You can do that because of this frictional force. Without friction, you wouldn’t be able to do many things in life.
Before discussing friction on an inclined plane, you must first know what friction is.
What Is Meant by Friction?
In physics, frictional force is a type of force that occurs due to the presence of two objects with surfaces touching each other.
So, this friction force is included in the type of touch force. The new frictional force will work when there is a touch on the two surfaces of the object, as well as being the cause of the emergence of this frictional force itself.

Every frictional force will always occur in the opposite direction to the tendency of the direction of motion of the object. The size of this force also comes from the level of surface roughness of the object itself.
If the surface of the object is rough, then the frictional force that arises is greater. Conversely, if the surface of the object is smooth, it means that the frictional force that occurs is also getting smaller.
The existence of frictional forces on inclined and straight planes can work on all types of substances, starting from solids, gases, and also liquids.
Static Friction on an Inclined Plane
One type of frictional force is static frictional force. This is the frictional force between two objects before they move.
In other words, this static frictional force works when the two objects are still or have not moved. For example, like when you push a drawer on a flat floor.
When you start pushing, the drawer sometimes doesn’t move right away, but even though the force is already working. This happens because of the static frictional force acting on the drawer legs and the floor.
Here, static frictional force will offset the push we give. Static friction will then change to a maximum when the object will move.
Not only on a flat surface, there is also friction on an inclined plane. Static friction on an inclined plane will keep objects stationary or not slide down.
In other words, this static frictional force makes objects stay in position and will slide when the static frictional force is at its peak.

Kinetic Friction on an Inclined Plane
Another type of frictional force is kinetic or dynamic. This type of frictional force in physics will work after the object moves.
The meaning of kinetic friction is a change or transition from static friction. when the static frictional force disappears and is no longer holding the object still, it will change to kinetic frictional force.
Still using the drawer example as above. The drawer will remain stationary despite a push due to the presence of a static force that compensates for the push.
However, when you increase the push, the drawer will move and the static friction will immediately disappear and then turn into kinetic friction.
In the case of an inclined plane, the magnitude of the kinetic force has exceeded the static force so that the object will move and slide down. When this condition occurs, the frictional force is no longer static, but has changed into a kinetic frictional force.
So, friction on an inclined plane can occur in static or kinetic friction. The tilt of the object will also not affect the magnitude of the frictional force. (R10/HR-Online)
