By adding different weights in both box and string it has been recorded the exact weight needed for the box to move. The weights that have been added until the box start moving at a constant velocity were measured. With the use of the acceleration due to gravity (9.81m/s2) the Normal and Frictional Force were calculate. With the use of this experiment some conclusions have been drawn. For instance the main result is that the friction increases if one of the following variables increases: the weight of the box, the size of the box and the weight that is being pulled. Although there are some other factors that affect the friction but they have not been tested in this experiment. For example the surface that the box is places on affects the frictional force that is applied on it. If the material is friction less then fewer weights will be needed to pull the box, on the other hand if the table is rougher then the friction will be greater and more weight will be needed to pull the same box. Introduction Friction is the force that appears when two objects come in contact. There are two types of frictions, the static friction and the sliding friction. The static friction occurs when
