## What Are Some Possible Sources of Errors in the Lab?

To find out mechanical advantage and efficiency of various pulley system To find out if there is energy conservation in a pulley system. Coefficients of Friction Lab Summary. You will be pulling with increasing tension until the object begins to slide and then you will keep the object moving at a slow steady speed. However, dθ is not also 0. Only you, who did the experiment, can make an educated guess about the size of dθ. The normal force is perpendicular to the contact force while a friction force is parallel to the contact surface.

A static friction force fs acts on an object at rest while. Other sources of errors were from the calibration of the sensor. According to her friction helps in understanding universalism: freedom, prosperity, and knowledge Tsing, pg29. Repeat the process for each of the two wide surfaces of the friction block being in contact with the track. Some possible sources of errors in the lab includes instrumental or observational errors. It can never be contained within the body. Ok so I adjusted my angle from 26.

Download file to see previous pages Static friction is denoted as Fstatic. Download file to see next pages Read More. An observational error example would be if the experimenter did not read the thermometer correctly when recording results. It only depends on the surfaces in contact. An example of this error is a thermometer used to measure temperature.

It can also transmit from the system to its environment or vice versa. I tried that and I got a value of 0. Coefficient of friction lab report. Neither you, nor the coeditors you shared it with will be able to recover it again. Using a 1000g mass and a ramp, pull the wood block up the ramp at 3 different inclines.

In general, this coefficient is less than that for static friction. The Motion Detector was placed on the track and positioned so that it could detect the motion of the block as it was sliding towards the detector. To investigate the relationship between ideal mechanical advantage and number of stands supporting the mobile pulley. Acceleration Coefficient of kinetic fricton. Lab 4: Friction Friction: Determination of µs and µk Interaction of two bodies on the surface always involves contact forces.

However, dθ is not also 0. An example of an environmental error is when an air conditioner in a room causes the table to vibrate slightly and this vibration causes the measurement to be slightly off. The attempt at a solution Do I just plug in my angle value of 26 into the theta's to get the answer? Friction Lab Investigating the factors of friction What factors affect static friction? What factors affect kinetic friction? Each of the boxes as well as the table should be cleaned thoroughly before the experiment. Only you, who did the experiment, can make an educated guess about the size of dθ. Inconsistencies in surfaces: The surfaces used were not uniform.

The box does not move until the tension in the string is grates than the frictional force. In order to eliminate all the expected errors, it is necessary to clean both the sliding surfaces. In addition to, a household device is crucial in the absence of electricity. The greater the mass is, the greater the static and kinetic frictional force is. There are two types of friction called kinetic and static friction. This lab will let you determine the coefficients of static friction and kinetic friction between different surfaces. Work, Energy, and Efficiency: Pulleys The objective of this experiment is: To explore the use of pulleys inmaking work easier.

In the present experiment, the priority studied is the precipitation of a product, sulfur, which forms when solution of hydrochloric acid and Thiosulfate are mixed. An introduction to physical science. The only thing that determines mu is the angle of the slope. The normal force is defined as the perpendicular component of the force exerted by the surface. Wood block: Any deformation in the shape of the wood block would affect the results of this lab. The continuous movements of the atoms and molecules within the body, where they randomly hit each other produce heat or thermal energy. The primary objective of the lab experiment to assess the conversion of the work into kinetic energy particularly works done by the underlying force of gravity.

The flow of information is critical in engaging the. To what accuracy did you measure that angle in radians? Measure force on spring scale. Be sure to do all calculations and express all angles in radians. Friction: Finding the coefficient of kinetic friction. The manufacture of the instrument is such that it can charge with the same speed as. Data Surface Hypothesis: The factors of surface, mass, and angle of inclination affect kinetic and static friction.
