Resistive Force of attrition by Ron Kurtus (revised 6 January 2006) Friction is a eviscerate that resists the move pillowcased by another(prenominal) force on an object. The requirement for friction is that the object essential be in co ntact with another object or material and an external force must be applied on the object in an crusade to move it. The type of doubtfulness determines the different types of friction, which be sliding, curl and fluid friction.

If the object does not move, the friction is considered static. If the force is adapted to move the object, the friction is called kinetic. The cause of friction is a combining of surface roughness, molecular hamper and deformation effects. (See sources) In sincere words, this piece says that friction is a resistive force (works against the directionof movement). It of course of action depends on the shape, construction and weight of the object it is res isting against. That is why at that place ! ar different types of friction. This lab was entirely roughly friction. Because the channelize query was: How does the sole of my shoe help me stop? So this was about the structure and material of the object. The rougher the sole, the faster itll make you stop. Aim We are going to find out if our...If you want to disturb a full essay, order it on our website: OrderEssay.net
