How do you increase and decrease frictional force?
To increase frictional force, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or increase the coefficient of friction by using materials that interact with more resistance. To decrease frictional force, you can use lubricants to reduce surface interaction, decrease the normal force, or use smoother materials to reduce resistance.
Does gravity have an effect on friction?
Yes, gravity affects the normal force between two surfaces, which in turn influences the frictional force between them. In general, an increase in weight due to gravity can increase the frictional force between two surfaces.
Is it possible for a frictional force to increase the mechanical energy of a system?
your question is not clear but fro what i could understand, i can tell you that frictional force always opposes motion of mechanical system ( so it would decrease the system's mechanical energy) therefore i can never increase it.
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 does weight affect frictional force?
Weight affects frictional force because friction is a force that opposes motion and is directly proportional to the normal force acting on the object. The normal force acting on an object is influenced by its weight, so an increase in weight results in a greater normal force and therefore a greater frictional force.

Frictional force will increase with increase in?
Friction increases as a function of velocity.
When do the frictional forces between two surfaces increase?
As they come into contact so tight friction would increase As roughness increases frictional force too increases.
Does gravity have an effect on friction?
Yes, gravity affects the normal force between two surfaces, which in turn influences the frictional force between them. In general, an increase in weight due to gravity can increase the frictional force between two surfaces.
How does weight and surface area affect the frictional force?
As mass increases Surfaces area increase so the gravitational force increase so the friction increase...............
Why machine parts oil occasionally?
to reduce the energy loss due to frictional force.
Is it possible for a frictional force to increase the mechanical energy of a system?

Does a frictional force between two objects increase with a force between them?
if you are talking about contact force, then you are correct. but if you are talking about some other external force,then the answer will be no. because frictional force only depends on the contact force between any two objects.
How can you show that frictional force depends on nature of surface in contact?

Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....
How do you decrease velocity of a moving car?
You increase the frictional force by applying the brakes.
Why does weight affect frictional force?
Weight affects frictional force because friction is a force that opposes motion and is directly proportional to the normal force acting on the object. The normal force acting on an object is influenced by its weight, so an increase in weight results in a greater normal force and therefore a greater frictional force.
