The fifth experiment under physics10L is all slightly rubbing. It is the contract that opposes the motion of a frame. It can also be described as a root for between to surfaces pass together. It is high if the surfaces atomic number 18 dry and rough and it is low if the surfaces are smooth and wet. Some basic facts about fiction is that when devil smooth surfaces rub together, there is a very wee friction, when two rough surfaces rub together there is to a greater extent friction and lastly, there is more friction if two surfaces are forced against each other.
In this experiment, the intentive is to determine the coefficient of friction (?) between contact surfaces (particularly wood to wood) as bingle body moves with uniform motion and to establish the relationship between the tip off of repose (?) and (?). This experiment has three parts with five win trials. The first frame-up is for the determination of the coefficient of friction (?), wherein the weight of the pile of wood is changing as well as the force that triggers the motion of the block in unending speed. The second setup is for the determination of the pitch of repose or the steepest angle for constant velocity of the friction. And the third setup is for the determination of maximum force that causes uniform motion.
The materials used in this experiment are string up that is attached to the wood and pan, pulley for the alignment of the string, protractor for the determination of the angle of repose, inclined plane that is also wood for the overall experiment, it is the object where the block of wood will glide and lastly, the meter arrest that is used for measuring the vertical height and horizontal infinite for the second part of the experiment.
To test the coefficient of kinetic friction, we used a small, wooden block. The block had a string attached to one face. This string was threaded over a pulley, and was connected to a pot hanger.
I notice that as the total mass of the block increases, the tension...If you want to get a full essay, point it on our website: Ordercustompaper.com
