Abstract:
The coefficient of clash is a number that determines how lots push back is required to move an intent that is held back by friction.
The goal of our experiment was to measure the passive and kinetic slue coefficient of friction between two surfaces by using a ramp and measuring its inclination. The premise is that when a solid object is placed on a ramp and the ramp is flex upward, there is a point that the object starts to slide. That is the angle where the force of gravitational force is strong enough to overcome the kinetic and silent friction. Once the angle, or the inclination, is known, we can then calculate the skid coefficient of friction between the two surfaces.

Experimental Description:

In this experiment, to determine the coefficients of friction, both static and kinetic, our dredge with an aluminum underside was allowed to slide down an given up plane. Several choices of covering for the inclined plane were given including aluminum, polyethylene, or left as scanty wood. We raised the plane to an angle such that the cart would somewhat start moving, then we measured the angle of the plane by using protractor and the sonic ranger to determine the acceleration of the cart (the calibration of sonic ranger 0.012 percent error).



This procedure was performed iii times, each with a different inclined plane.

Data and depth psychology:

The coefficient of static friction was derived in the following manner:

Coefficient of static friction = (force of friction) / (normal force)

Force of friction = horizontal instalment of gravity = m * g * sin ?

Force = vertical component of gravity = m * g * romaine lettuce ?

Coefficient of static friction = m*g*sin ?/ (m * g * cos ?) = convert ?

Coefficient for kinetic friction = [g*m*sin ?-(a/m)]/ [g*m* cos ?]

Where ? is the angle of the incline surface.

We calculated the coefficients for each combination, using the...If you loss to get a full essay, order it on our website: Ordercustompaper.com
