Because space is a vacuum, the planets have no frictional force to slow them down, unless they collide with another planet. This is why earth does not stop and plunge into the sun.
The forces involved in the orbit of a planet are gravity and centrifugal force, but not friction

Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
What is the meaning of frictional force?
Frictional force is the force that opposes the motion of an object when it comes into contact with another surface. It is caused by the interactions between the surface molecules of the two objects rubbing against each other. The magnitude of the frictional force depends on the surfaces involved and the normal force pressing them together.
Is frictional fource contact or non contact force?
Frictional force is a contact force. It arises between two surfaces in contact with each other and opposes the relative motion or tendency of motion between them.
How can you show that frictional force depends on nature of surface in contact?
You can demonstrate that frictional force depends on the nature of the surfaces in contact by conducting an experiment where you measure the frictional force between different surfaces. By varying the types of surfaces (e.g., smooth versus rough), you can observe how the frictional force changes accordingly. The coefficient of friction, which quantifies this relationship, will be different for each pair of surfaces, highlighting the influence of surface nature on frictional force.
Why the rough surface have the greatest frictional force?
A rough surface has a greater frictional force because the asperities or tiny bumps on the surface interlock with each other, causing more resistance to motion when two surfaces slide against each other. This increased interaction between the surfaces results in a higher frictional force compared to smoother surfaces.
On what does the frictional force depend?
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.
What happens to the magnitude of frictional force when two surfaces are pressed hard?
When two surfaces are pressed hard against each other, the magnitude of the frictional force typically increases. This is because the increased normal force between the surfaces leads to more intermolecular interactions, resulting in higher friction.
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
Explanation of three blocks kept above each other with frictional force between them and acted by force?

What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
Which frictional force is self adjusting force?
The static frictional force is a self-adjusting force. It increases or decreases to match the applied force, preventing the object from moving until the maximum threshold is reached.
What has frictional force needed to start an object at rest into motion?
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
