What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
How are friction and mass of an object related?
force of friction= coefficient of friction x force of normal force of normal is mass x whatever force that is acting on it (usually gravity)
Why does a larger mass cause more friction?
Friction force (f) is the normal force by the surface on the object multiplied by the coefficient of friction.f = N1S u
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
What are the two factors that determine frictional force?
two variables are : the surface type and the mass of the object. So the more mass an object has the less friction it has. The less mass an object has, the more fiction it has.

How are the force of friction and the force necessary to move an object related?
In any given case, friction can produce AT MOST a certain amount of friction; if the coefficient of friction is known, this can be calculated as the normal force multiplied by the coefficient of friction.The force necessary to move an object must, of course, be greater than this maximum friction.
How do you apply friction?
Friction acts in the opposite direction that the object is moving or trying to move. The force of friction is calculated by multiplying the normal force of the object, usually mass times gravity, by the coefficient of friction.
Is friction affected by the amount of surface that is touching?
No: this is a common misconception Friction= Normal force* Coefficient of friction where Normal force= Mass* Acceleration due to gravity* Cos(angle of surface) and the coefficient of friction is an intrinsic property of the surface Therefore, only the mass of the object and the surface composition affect friction
What 2 things determine the friction between to objects?
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
What are the two factors that determine frictional force?
two variables are : the surface type and the mass of the object. So the more mass an object has the less friction it has. The less mass an object has, the more fiction it has.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
What does 'co-efficient of friction' mean?
The amount of friction force that acts upon a body of mass depends on two factors: the property of the object and the normal force acting on the body. "Coefficient of friction" refers to the property of the material; in other words, the higher the coefficient of friction, larger the friction force is. The force of friction can be represented by this equation: FF = µFN. µ in this case represents the coefficient of friction. It can best be described as the numerical value that equates to the property of the object we are dealing with. µ does not have units; this reinforces the idea that it is just a numerical value that represents how "rough" or "smooth" the surface of an object is. Simply, the coefficient of friction is a way to describe, symbolically and numerically, how hard it is to move an object along a surface that the object is in contact with.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
What can effect the amount of frictions between two objects?
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
