2 kinds of forces?
Gravitational force, which is the force of attraction between two masses, and electromagnetic force, which is the force between electrically charged particles.
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.
What is an non-example of Friction?
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
Why frictional force is known as non conservative force?
Frictional force is known as a non-conservative force because it depends on the path taken by an object and not just on the initial and final positions. Work done against friction to overcome it does not depend solely on the initial and final positions, making it non-conservative. Energy is dissipated as heat in overcoming friction, leading to a loss of mechanical energy.
On what does the frictional force depend?
Frictional force depends on the nature of the surfaces in contact and the force pressing them together.

Is writing on a paper a frictional force or muscular force?
i am sure that it is not frictional force.....

What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional 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.
What does the frictional force vs normal force graph reveal about the relationship between these two forces?
The frictional force vs normal force graph shows that there is a linear relationship between the two forces. As the normal force increases, the frictional force also increases proportionally. This indicates that the frictional force is directly proportional to the normal force.
How can one consider a frictional force on a track as constant while frictional forces are non conservative?
This is a very good question. A conservative force is defined as a force that doesn't remove energy from a system. Such forces as a spring force are conservative. However, wherever a frictional force is exerted, heat is produced. It takes energy to make heat, and the energy comes from the kinetic energy of whatever objects have frictional forces exerted upon them. A frictional force will eventually remove all of the kinetic energy from a system. However, a frictional force is constant. The force of friction is defined as the coefficient of friction times mass times the gravitational constant. (The coefficient of friction is represented as the greek letter mu). Regardless of the remaining Kinetic energy in a system, the frictional force will not change, thus a frictional force is constant, but not conservative.
