What is the coefficient of friction between the block and the ramp?
Again, the surface contact between the block and ramp was assumed to have a coefficient of friction µ = 0.30.
Is there friction on a ramp?
When an object is placed on a flat incline or ramp, it will not slide down the surface if the force caused by gravity acting on the object is less than the resistance from friction. Since the object does not slide, the resistance is called static sliding friction.
How do I calculate the coefficient of friction?
The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N.
What is the formula for coefficient of friction?
μ = F/Ncoefficient of friction, ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together. It is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/N, where F is the frictional force and N is the normal force.

Homework Statement
You do 2.2 kJ of work pushing a trunk at a constant speed 3.1 m along a ramp inclined upward at 22 degrees. What is the frictional coefficient between the trunk and the ramp?
The Attempt at a Solution
Since the trunk is moving at a constant speed, the forces pulling the trunk down the ramp must equal the forces pushing it up the ramp.
Answers and Replies
1. that would not give force - work/speed has dimensions of force per unit time.
How to find static coefficient of friction?
A clever way to determine the static coefficient of friction is to start an object sliding down a ramp. The component of gravitational force that causes the object to just start moving is equal to the resistive force to keep the object stationary. That is the static force of friction. Note that you must record what the two surfaces are.
How to find the friction equation?
The friction equation is Fr = fr x N, where Fr is the resistive force of friction or the amount of force required to overcome friction, fr is the coefficient of friction between the two surfaces, and N is the normal or perpendicular force pushing the two surfaces together. If the force pushing to surfaces together is gravity, then N equals the weight of the upper object.
What is the coefficient of friction between two surfaces?
The coefficient of friction between two surfaces is a number that determines how much force is required to move an object that is held back by friction when the two surfaces are pressed together.
What is the coefficient of friction?
Note that you must record what the two surfaces are. The coefficient of friction is always for two surfaces. For example, you could find the friction between wood and steel, wood on wood, rubber on wet pavement, and so on.
What is static friction?
Static and kinetic friction. For a sliding object, the static co efficient of friction results in the force required to start the object moving. Once the object is sliding at a steady rate, the kinetic coefficient of friction results in the force required to keep the object moving at that velocity.
