Sandpaper overall was the biggest contributor, yielding the highest coefficients of all the surfaces done by different groups in the experiment. Why are unsigned numbers implemented?

Your cache administrator is webmaster. A wood block with a hook attached to one end. Attach the graphs to the lab report. The equation for static friction is coefficient of static friction multiplied by normal force.

The same wood block on the same sand paper at the same humidity will start moving at different forces when we repeat the experiment, rendering the idea that static friction is The system returned: (22) Invalid argument The remote host or network may be down. This experiment measures the friction force in grams for simplified calculations. Procedure To begin this experiment, we first set up the LabPro computer program to collect data for 10 seconds at 60 samples per second.

That makes measurement local rather than universal. –Gert Nov 1 '15 at 22:46 add a comment| active oldest votes Know someone who can answer? Place your estimate of µs for each case below. With modern technology, is it possible to permanently stay in sunlight, without going into space? A 400-gram weight is placed on topof the block to make measurements easier.

a. Next, we pulled the block horizontally and initially began with a small amount of force and gradually increased our force applied until the block began to slide. Kinetic friction isdefined as:  f  k  = µ k  F n (2)where µ k  is the coefficient of kinetic friction. Please try the request again.

Hot Network Questions Why is it a bad idea for management to have constant access to every employee's inbox?

Conclusions As the results show, static friction is generally significantly larger than kinetic friction.

Friction acts in the opposite direction of the movement of the object and parallel to the surface.

Is 'if there's any' grammatical in this sentence? Then, we placed one of the sides of the block on our chosen surface and placed an appropriate mass on it to increase normal force. (We ended up using a felt

Finally, we repeated the entire process on an additional two different surfaces, leaving us with a total of six graphs displaying the different static and kinetic coefficients of friction. In order to obtain any kind of useful measurement, the experimenter has to pull in an excruciatingly slow motion.

Why is the spacesuit design so strange in Sunshine? The normal force a. Kinetic friction occurs at the spot where the two surfaces come into contact with each other and it opposes the object that is moving relative to the other surface. The coefficient of static friction is higher than that of kinetic friction because it requires more force to get an object moving than it does to keep it moving.

As a class, many different pairs of surfaces were tested in order to determine both the static and kinetic coefficients of friction. Static Friction Static Friction is the friction present when two surfaces are touching and neither are moving, even though a force parallel to the two surfaces is being applied to one We repeated these exact steps using the opposite side of the block (the opposite side of the block used different material than the initial side) on the same surface. How is the normal force calculated? 6.

In all cases, the coeff of static friction was greater than coeff of kinetic friction, as hypothesized. 2. A string is then attached to an eye-bolt at one endof the block and the other end is fastened to a spring force scale. Use the slope of the line to estimate the coefficient of static friction (µs) for the two surfaces involved. The system returned: (22) Invalid argument The remote host or network may be down.

AnOhaus Pull-Type Spring Scale (Model 8003-MN) was used in this Source:OhausCorp.www.ohaus.com  Figure 1.2 Figure 1.3 Force vector diagram on thewooden block system experiment, which has a least count of 25 grams (see Please try the request again. We tried to pull the block at a constant velocity afterwards. Afterwards, we examined our graph and determined the maximum force of static friction and the force of kinetic friction and recorded our results.

Additionally, the coefficient of kinetic friction is defined as:tan θ = µ k  (4)where theta is the angle between an incline and a horizontal surface at which an objectwill slide along the One issue that we ran into was that sandpaper on carpet dragged in such a way that the force required to pull it was prone to spikes and sharp dips, because Carpet has highest frictions, then commons tile, then table. And if there are any other limitations what would they be, because so far I am stumped.

Can the normal force ever be greater than the weight? 2.
