What is the mathematical equation for friction?
An important formula is that friction = (coefficient of friction) x (normal force).
What is the math shape when it looks like a bow?

How can you calculate?
One formula that is frequently used is: friction = mu x Fn, where mu (the Greek letter mu) is the coefficient of friction, and Fn is the normal force - the force that pushes the surfaces together, perpendicular to the surface. The coefficient of friction depends on the combination of materials; you can look it up in tables for different combinations of materials; or you can determine it experimentally.
Why if you increase the angle of the inclined plane the acceleration of the trolley will increase?
If the angle is increased, the tangential component of the weight will increase, while the normal component - the one that causes friction - will decrease.
How can normal cells become cancer cells?
They can be mutated through irradiation.
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
What are the two kinds of friction?
There are two types of friction : static friction and kinetic friction. Static friction occurs when two objects are touching but are not moving relative to each other. For example, static friction can prevent a box from sliding down a slope. The static friction between this box and the slope (and between any objects) can be calculated using the equation : Fs = µsN where µs is the coefficient of static friction and N is the normal force. Kinetic friction occurs when two objects are touching and moving relative to each other. For example, the kinetic friction slows down a box sliding down a slope. Also, when two surfaces rub together, there is kinetic friction. The kinetic friction can be calculated using the equation: Fk= µkN where µk is the coefficient of kinetic friction and N is the normal force.
Definition kinetic friction?
Friction generated between two dry surfaces in contact during motion. Kinetic frictionis a product of the coefficient of kinetic friction and the normal reaction force. It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.
Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.

It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.
A hockey puck has a coefficient of kinetic friction of mk .1-. if the puck feels a normal force (fn) of 5N what is the frictional force that acts on the puck?
This type of problems about friction are extremely simple: You just multiply the normal force by the coefficient of friction to get the frictional force.
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.
Why Kinetic Friction is constant?
Because kinetic friction is proportional to the weight of the object moving, not the speed of the object. While it definitely seems like something that moves faster should be losing more energy to friction, friction only depends on how much the two objects push against each other, not how fast they touch. Imagine what would happen if hockey players slowed down due to increasing friction as they skated faster. **Don't confuse pressure with the force of friction.** Pressure = Force/Area f = u*N (N is the normal force from the surface)
What is the effect of decreasing the surface area of the block in contact with the table on the coefficient of kinetic friction?
there is no change.the coefficient of friction is independent of surface area.the matter will change only if normal reaction changes
Does normal force effect kinetic friction?
Both are forces, both are related to Newton, but no on the same rules, the normal force is a correspinding force to the gravitational field affecting the object, while the friction is the resistance of the surface.
A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
What is the equation for sliding friction?
fk = uk*N Where fk = force of kinetic (sliding) friction uk = kinetic frictional coefficient (dependent on 2 materials sliding past each other) N = normal force (force being exerted perpendicular to the surface across which the object is sliding)
